Cosmology: A Big Bang and the Beginning of the Universe
HTML-код
- Опубликовано: 25 авг 2024
- If we want to learn about the universe, we have to start at the very beginning. How and when did the universe begin? Is it even possible to know about such things? Yes, it is! That's what cosmology is all about, the origin and development of the universe. Let's go over what astronomers know today, and also mention what we don't know yet!

thanks now i can make my own universe!
I know it's still young but I wonder anyway: how's your universe doing?
@@Vagabond-Cosmique pretty good. Still waiting for it to cool down but apart from that it's alright. How about yours if you made one
@@ee2542 Sadly, mine is still just an idea, blossoming in my mind. Hopefully, I'll get to make it a reality soon enough, but I'll probably have to be patient.
I wish.

So this is a serious question, why in Professor Dave's sake are these Videos getting these low view counts? This content is not university level but all the videos are a good precurser to whichever field one wants to know more about and to get started. People should really appreciate such stuff way more ..
well it's pretty new still but i'm trying to get the word out! please tell your friends!
Totally agree. This channel deserves more views and subscribers. Scientific illiteracy is a major problem even today, in my opinion.
For me most of this is over my head,plus I'm 72 and only listen to mostly the professor debunking the ignorant flat earthers and astrology. funny how some people don't like what he says .so they don't understand what he says and get mad .instead.typical behavior id say.IE southern folks. Lower credit scores in the south,lower iq and over weight and a church on every corner. Am I stereotyping??
This channel is better than a lot of other popular RUclips science channels. It goes into much more detail, and avoids the trap of using bad analogies or trying to hard to be funny with cheesy jokes.
@@harrydoherty8299 I am also 7 decades old and anytime I encounter a flat earther or science denier in the comment section of any youtube video I may be watching, they get directed to all manner of Daves excellent videos, hoping they at least take a look. Even if they don't, that doesn't stop me from watching Daves videos. The series above (playlist already exists), is a favorite of mine.
The Big bang is such a weird thing to imagine. Especially T=0. Its so incredibly strange and for some reason I'm getting anxiety from it, because my mind can't comprehend it. Great Video!
Lol same
Same whenever I try to imagine nothingness I get a headache
Yeah I feel the exact same way! There's actually a term for it, "apeirophobia"...
Is it more difficult to image t=0 or the time has no beginning? What about absolute nothingness vs infinite space. When absolute nothingness means there was no space/time. Crazy
@@briangale404 I'm reminded of a quote by Blaise Pascal:
Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed.
Also, whenever I hear the phrase "spacetime", I'll always think of this channel:

@@whomerdoodles fantastic! Thanks for asking. 👍🏻
One of the things I like about science is that it’s a humble philosophy. When scientists don’t know things, they admit it outright to everyone. That way, we know what we need to learn in the future. It makes scientists trustworthy.
History's record of bloody dictatorships should show that belief one is never wrong makes one capable of great wrongs.
After watching this video my grandmother turned to me with a confused look on her face and said, "You really believe all this stuff? This makes more sense to you than creationism?" Science education is much needed, thank you for this video Professor Dave!
Creation actually makes more sense because you can just say God did it" and that is the answer. It's easy and basically anyone can understand it without any thought.
Understanding the Big Bang is hard, requires knowing math, and having an understanding of physics.
Of course the creation story is BS, but i understand why a lot of lay people say it's easier to understand
@@nathanmckenzie904 I completely agree, you have hit the nail on the head!
@@nathanmckenzie904 OK, saying god created the universe may be simpler, but assuming there is a god rise an impossible question to answer, what, who, when did this god was created? And that's a problem way more complex that answering the big bang because we don't have anything to prove God existence and even less (that's really nothing) to be able to understand what created it.

@RadioTSM {Operator Teddy Timis} lol the agreed upon creation story does not necessarily contradict this, but okay neckbeard
@@earlysda and then he says earth is flat
Yeah no shit that man deserves to be worshiped
@@earlysda That reason you say it is not accurate it is because you do not understand it. People like you prefer an easy answer to everything in a black and white view of reality. This is indeed a complex and somewhat difficult to understand even was an engineer students that use a lot of mathematics and physics. No, a a scientific theory is not the same as the colloquial word for theory. A theory have evidence, proof, mathematical models and scientific peer review that are constantlt correcting each other and inproving their argument and gaining new evidence. So, instead of throwing a biblical verse or any quatations better use a peer or data that can be review and seen by anybody especially professional to actuall see some proof and modify said theory.
Professor Dave, thanks for making your videos they are great. You're doing a great service to us english speakers teaching these scientific principles in such an understandable way.
Question about the last part of this video though, isnt oxygen required for ignition? Or was oxygen also one of the atoms created as part of the gases when fusion was possible?
in this context it's not ignition like combustion, it just means that it's hot enough for nuclear fusion to begin
I see, thanks for the explanation.
I like cosmology. This is a good explanation with good animations to help us understand.
"No matter how much you believe it to be true, or how elegant and well versed its mathematical and geometrical model may be, a theory proposed in areas where no human experience is possible or attainable, will never be anything more than naturalist mythology! No better than the myths of creation adhered to by the tribesmen dancing around the fire praying to a totem in the forests of Africa."

@@Moath1277 You can't call yourself a doctor in the sciences if you constantly spew religion.
Tommy Hubbard science is something, and naturalistic metaphysics is something else my friend
It was explained in the video that they don't have conclusive idea on what happened before 10^-36 of a second. After that it's purely theoretical until the first 17mins. And from there the events can be replicated on a particle accelerator. No bold claims were made like some sort of mythology as you describe. And they are certainly willing to discard the theory if evidence for something else comes to light. Scientists do real work in the name of science, they don't deserve to be compared to false prophets.
@@Moath1277 Interesting quote. Depends on what he means by human experience. We will never experience walking on the surface of the sun but we can see it with the right equipment. With other equipment we can examine the origins of the universe.
I love this so much. The sheer AWE of it. But it also terrifies me to my very core.... the idea of "nothing" is just so hard for me to not be afraid of. Irrational fear unfortunately.
It’s nothing to fear
@@mmccrownus2406 yeah right
It's perfectly rational.
@@idiosyncraticlawyer3400 In hindsight, I concede to that. But fear of concepts (which only exists in a mind) is borderline irrational. Maybe it's more a "disorder".. since it can literally trigger my fight or flight system just thinking to analytical and logical towards it.
@@arsenic1987 Fear of fear itself?
I haven't thought about how the universe can expand so quickly in such a short amount of time. But when I apply the time-dependence of the Hubble parameter for a radiation dominated universe ([d/dt a]/a = 1/2 1/t), everything makes sense lol.
I've watched MANY youtube videos on this subject and this is by far the best. Dave you have an uncanny knack for teaching, thank you!!!
Really? I'm glad I came across this one first then :)
You musings about "no thing, or is it some thing" reminds me of something we listened to occassionally in the missile business. "The missile knows where it is at all times. It knows this, because it knows where it isn't."
Is that seriously how middle guidance works? That’s really interesting
This is amazing. I've never seen such a clear and concise explanation of complex phenomena that can be understood by a layperson like me. Well done sir.
You do some incredible explaining on your videos. Keep them coming!!!!
I would note that the first thing, the first "point", is not necessarily an uncaused cause. Its cause is unknown, and currently unknowable. Perhaps there is no cause, perhaps there is. We shouldn't really suggest that one or anther is more likely because we simply do not know. It may be that we can never know. When we don't know, anything could be possible and we wouldn't know. This is the inevitable problem with all cosmological "proofs". You can't extrapolate from the known into an area that is undefined. It's a black swan fallacy on a grand scale.
Good point.
I love the format of your videos. You cover these complex topics at a level that most people can understand and still make them entertaining.
Imagine how hot your oven would have to get for it to take ~100,000,000 years to cool down just enough for matter to exist.
Burn your popcorn at those temps, the stuff just ceases to be.
Professor Dave is so important to the world...
Why does it feels like I have understood everything & absolutely nothing at the same time! It's really weird 🙂
Greed.the statement sounds contradictory but understanding some things and not understanding the others happens, which makes sense
Imagine your sitting in your living room and a universe just pops into existence in front of you
(I know that you wouldn’t see this but it’s a joke)
I been interested in studying astronomy and cosmology for right now and I saw your channel. Your channel made this more interesting and actually made me realize how complex and vast the universe is and I still have a lot to learn from it. But I do hope this continue. I want to prove that I can be become the best astronomer the world has ever had. So after a few years, when I stumble again on this comment. I hope I reach my dream and becoming what I truly wanted.
I'm 65 and even after watching this video I still don't get it. Nevertheless, I find it really fascinating and I hope you will continue to produce such great educational content.
This video definently deserves more views....
This has been out for two years and I have never seen it even though I watch your videos daily just because they get recommended so often. Lesson learned. Subscribed, liked and hit the bell like I should have done a long time ago. This video is aweso... ooooo chemistry!
legitimate question, in what frame of reference are these time figures like "17 minutes" coming from? with time being so relative it seems odd to be able to say something happened in the early universe for some absolute universal length of time experienced by all particles within it.
The universe was nearly homogenous for a lot of it.
My breakthrough in understanding the big bang was the fact that our conception of time breaks down at that point. I mean, who knows! To us and our calculations, all those forces broke apart within a second. Maybe to that expanding and cooling energy, it took billions of relative years.
I don't know enough to know. But it makes me wanna know!
wow, you explained it very simply. had various sources to read and this is the best! you have a precious gift in teaching!
I’m loving this. Reminds of watch bill nye videos in elementary school. Someone give this man access to a tv network
Wow great tutorial, you're by far my favorite RUclips teacher. You make understanding incredibly difficult things understandable to people who aren't super smart.
I can only imagine what things we will learn in the next 100 years considering what we've learnt in the last 100 (that's if we're still here and the planet is still habitable...)
I'm going to look up the next one now! 10/10 good work Dave 👍
Thanks doc your lessons are just incredible well done that anybody can understand them, I wish they were made compulsory in our education system.
Question from a layperson who simply watches these videos to be fascinated: I have heard several times lately that the speed of light is allegedly not only the highest speed we were ever able to measure, but also the highest speed that anything in the universe can have. I have not yet seen an explanation for how we are able to know this with certainty (or at least no explanation I was able to understand), but I was willing to accept it as a given for now. Here, however, you said the universe expanded to be about 600 light years across, within just about 17 minutes. How is this possible if nothing can move faster than the speed of light? Does the expansion of the universe at such a rapid speed not imply anything moving outwards at such speeds? Or did different rules apply back then because pretty much nothing we know today had formed yet?
Check out my special relativity tutorials in my modern physics playlist! It is indeed the universal speed limit as you'll see there. It limits motion within spacetime, not the expansion of spacetime itself, however.
@@ProfessorDaveExplains Thanks, I watched them! I wouldn't say I understood everything, and how the universe or spacetime was able to expand that quickly is still hard to imagine, but many things I was only vaguely familiar with before have become much clearer now. I really appreciate what you do, and it's amazing how many topics you cover. I have a feeling I'll be going through quite few of your playlists in the near future.
@@WiiAndii Closest I can get to explaining it myself is imagine spacetime being the outside of a balloon as you inflate it. all points drift apart. There is no "speed limit" on how fast that can go. The speed-limit applies to traversing the surface of the balloon from one point to another.
It's really beautiful when you think about it.
Despite the universe being full of shit that could kill us, despite the process of evolution being a long and difficult task were any 3 seconds from then could cause extinction- despite all the disasters, plagues etc. We made it. We've come so far.
And that's a comfort.
And it all started from this.
Yeah
It makes you wonder
Just what is there more to learn?
Hi...I Had been going through various videos which could possibly explain all these concept of big bang nothingness and it's correlation... And to my surprise I found the most relatable explanation here...truly awesome and phenomenal explanation... I just started with some arbitrary videos and thinking back I realised I actually lost the count...These videos are kind of awesome...keep going..
I just love how these tutorials are both accessible and deep down into the subject !
During Inflationary epoch it goes to light years within fraction of sec.. how can it be possible since nothing can travel faster than light.?? I guess Relativity was applicable during big-bang..
So special relativity applies to objects moving within spacetime, it says nothing about the behavior of spacetime itself, so inflation actually doesn't violate any laws of physics! Pretty astounding stuff, though not well understood, particularly not by me.
Inflation doesn't make spacetime travel anywhere, it's literally making more 'anywhere'. So, it's not going faster than light, it's adding more space, so to speak. And this addition isn't located 'from somewhere'. It's everywhere. Imagine every single Planck length sorta breeding new Planck length, if you want an analogy to help you grasp why it would grow so big in so little time.
Dark energy speeds up exponenetially and can separate space faster than light
@@austinlincoln3414 Its not about just dark energy. The speed of light is measured in space time. During Infationary epoch the space time itself is in making.
That's why it can be more than speed of light.
Great video, watched it with my 5-year-old, trying to get him to passively take in as much science as possible...
Genesis 1:1 "And on the first day, from a single point, space and time was formed, and the universe liked it."
I just realised how thin our understanding is about the way universe begun and that understanding is not grounded on very solid principles either.
Did you actually watch this?
It is grounded on solid principles, this model is heavily supported lmao
@@ProfessorDaveExplains yes sir, I did and still genuinely believe what I said.
@@amashmlk7543Well, then you're just stupid.
@@amashmlk7543 then you're very ignorant
Thanks
Wow.
10^-43 seconds is ~1 plank time, the time it takes light to travel one plank length
That long after the universe was created, it was ~10^32 degrees K, which is ~100 nonillion degrees K
At 100 nonillion degrees K, the heat waves that would be raiding of of the object would be 1 plank length long, which is technically the hottest something can get.
So wow.
No one could have put this more technical and yet simpler than you did just in 15 min. This is an art you have been blessed with. Do not stop!
I don’t understand why people are so opposed to the big bang. We’re looking at what we can see and extrapolating what could’ve happened. Sure, we might be somewhat off, but it’s better than sticking your head in the sand just because you can’t immediately understand it.
Unfortunately I’ve noticed lately it’s become more popular for people to deny science that they can’t comprehend. As if a common layperson is supposed to be able to understand theories proposed by people with PHDs in astrophysics...
Great vid as always
Could quantum fluctuation even be possible in the time before the big bang when there was no universe for a particle to pop into existence to?
the quantum flcutuation is conejcture we don't know but its possible its really mathemtically complex there might hav ebeen something before big bang or nothing we don't know
This is soooooo goooooooddd 😭❤️
If a universe with higher vacuum energy experienced vacuum decay starting from a point, and vacuum decay spreads at light speed for that universe, would the interior of the region that has already experienced vacuum decay look substantially different from our own universe?
Cosmic inflation could be explained as regions of vacuum decay starting from different points meeting each other, and later cosmic expansion as a difference in spacetime metric from the scale of the universe undergoing decay.
Professor Dave is the best!

Where did the energy come from to ignite the ‘Big Bang?’
@Cobweb Recordings I hope will do someday.........before I die.
In my opinion, information and energies contain inherent, inert disparities and potentials that could manifest in a confined scenario. These potentials may have compounded in the singularity inception, forming the initial potent reaction. This is not a 1+1=2 circumstance, the subtle properties of the potential energies and information are catalysts that cannot be easily gauged. Differences between energies and information created an emergent property, and this impulse was converted into explosive power. The potential that resided within the informational and energetic gaps of the singularity was violently and mathematically extrapolated, probably due to forced quantum entanglement and high density in such close quarters. In other words, there was more to the original singularity than "a simple ball of energy", it contained enormous hidden potential.
@@mace9930 no
Nello Kiko I don’t think you were paying attention when Dave explained how the Big Bang came into existence. It was a quantum fluctuation, similar to virtual particles popping in and out of existence as explained by Heisenberg’s Uncertainty Principle. He did say though that the very beginning is not understood and it’s mainly conjecture until we get to 10 to negative 36 seconds. That’s my understanding anyway.

Dave, I got a question: Did the universe expansion slow down as a result of gravity breaking away?
Its okay if its not yet known. Flatties think we know everything. We dont. There are lots of things we dont know.
@@TuriGamer I mean at the symmetry breaking
"Before thare was time, before there was anything, there was nothing. And before there was nothing there were monsters"
Professor Dave explains a lot..but he can't explain how he has that phenomenal hair.
With so much mass condensed into a relatively small space - what is the meaning of time and seconds? Isn't the universe at these stages like a massive black hole that wraps space time so much that to talk about seconds is meaningless?
that's a pretty good question! perhaps time dilation was so extreme back then that those initial moments would have seemed much longer to anything that could have experienced it. but of course nothing could have possibly experienced it. but as to the physics of it, i really don't know!
Before "ordered time" there was "unordered time).

before the big bang:
"Nothing was never anywhere. That's why it's been everywhere. It's been so everywhere you don't need a where. You don't even need a when. That's how every it gets."
-Bill Wurtz
History of the entire world, I guess
As a Christian, I think you have explained this very well. But I am still a little confused regarding quantum fluctuations. There was completely NOTHING before the Big Bang. How can something come from nothing? Quantum fluctuations have been observed in our universe(where there is something), but out of completely nothing? How does that work. If anybody who is reading this is willing to explain, please do so in a serious, scientific manner, without throwing stuff about theology(which you don't understand) in my face. *Please.*
P.S: Quantum Fluctuations happen in our timeline. But before time?
So I think there was something before the big bang but we don’t know what so we just say that there wasn’t anything
(Correct me if I’m wrong)
We don't know so we shouldn't jump to conclusions like religion
The Big Bang theory does not posit that "nothing" existed. Rather, it is everything, but in an extremely condensed state.

@@Gfish17 You do not understand. Genesis is poetical. It is a mere poem for God. Evolution does not contradict Christianity, which is something that many Christians do not understand. The 6 Days of Creation are not literal. Everything that has lead to us was planned by God when he popped the Universe into existence. The concept of God cannot be explained exactly, because we do not know what he did exactly in the beginning. This is why when we talk about Him we speak poetically: "In the beginning, there was nothing. Nothing but the silence of an infinite darkness. But the breath of The Creator fluttered against the face of darkness, whispering: Let there be light... And light was."

Nice job summarizing the epochs, as well as including which parts are unknown hypotheses, which are more theoretical, and which are supported by evidence. Some folks will miss those distinctions, and more importantly, how they are connected and how we have already eliminated multiple hypotheses that did not lead to observable/testable results.

You must understand the Bible is not a science book. The Genesis is poetry, not history. Ask the majority of theologists. Your Christian teachers are not theologists. They probably just did a shitty religious seminary where nothing was explained to them. God is not a sky wizard. God is physiscs. God is time. God is everything. This is the concept of God.
“Nothingness is the absence of itself”~J.P. Sartre
I watched this video and it made me think of what we really know.
A blind man once told me, "Try to look through your elbow and you have nothingness." But I think that the answer to the start might be beyond our thinking. What if our universe were a mirror to another universe, for example? I mean, human beings should not be able to imagine the start of everything when there are an infinite number of dimensions and an infinite amount of space in each dimension.
Do we even know if a fourth-dimensional or higher being would exist if there are an infinite number of dimensions?

Thank you 🙏 Professor Dave!! This is essential information for the progress of humanity, indispensable information ℹ for the entire globe 🌍. Religion is no solution for the requirements of humanity in the 21st century. The scientific method has made religion obsolete, it is for primitive minds.
the fact that the universe was visible but was transparent makes me feel more in touch with the world than any religious experience of my life. thats soooo weeeeeiirrrdddddddd. HAIL DAVE

Amazing video Dave, I'm looking forward to more. Always loved your channel and your vids, been subscribed soon before 1mil
This is sort of the only reason I still hold onto the thought of a god. Or gods. Or goddesses, or whatever. Nothing is something because it’s everything around us, but how did everything around us come to be? We all need something to make another thing. So how did something just- appear? But, that begs the question. What created gods? Goddesses? Everything? Is life as we know it nothing at all? When did it all start? Like. Seriously, when? How? I know he tries to explain it, but it had to come from something. How did nothing turn into something without another thing? You can’t say molecules, what made molecules? What started that? Ugh, this hurts my head.
This isn't "something from nothing". It's "everything very condensed to everything expanding".
Okay so basically you're just pulling the same god of the gaps that every religious person uses. Got it. Maybe you should be honest with yourself and say "I don't know" instead of making stuff up for how things came up to be.
@@Daniel-wr9ql I’m not, I’m asking. I gave up on religion 2 months ago, after this was posted. I’m just wondering. I don’t know, that’s why I’m asking
@@zealousforyah1008 where’s the proof? Give me proof without the Bible lol.
Honestly growing up as a Creationist, this scares the crap out of me. Psychologically stretching from 6,000 years to millions is hard. I'm going to watch this a few times so my mind can envision it. Thank you for taking old my old hero Kent Hovind. What a liar he is. 😂😂😂😂😂👖🤔🚿😜🏥👹👹👹
I like the white cliffs at Dover: every single speck of chalk is a dead planktonic organism that died and sank to the bottom, and those cliffs are _massive._
@@williamchamberlain2263 i like the pictures of proclids in nebulas, they are the first step in the formation of a star and possibly a solar system. Once that was the earth, a slightly more dense region of dust and gas left over from previous supernovas. We are the tiniest most ephemeral of things in comparison but at least we have a chance to comprehend it.
Two questions that might be answered in the next video: (1) were those earliest photons detected, or merely theorized, and (2) if the universe continues to cool, what do you think could be a new force splitting off and what could be the implications? Heading straight to the next video, thanks! (PS, I just learned about you on The Thinking Atheist.)
I love these videos, and I love the information presented and how easily digestible it is, but every time I hear "tutorial" all I can think about is Alan Tutorial and I immediately lose focus on the video lmfao.
I can feel all apologists starting to butthurt)) I mean how many of them knew all that and tried to understand, before denying it all and saying - god did it. None.
@Brody Massey that would render bible, quaran etc as absolute BS. If it's not any of these gods, which is it then? And then raises a question: why such god is even necessary?
The theory behind BigBang was intro’d by a Catholic priest, -seems like something noteworthy.
I didn't had headache when I came here, thanks for the gift 🤕
from 1:53 onwards, I was getting hypnotised.
Before time, before the existence of the universe there was and is the unknown unknown. The creator YHVH
Proof
People from other religions could just as easily insert their god.
Nah, I'm pretty sure it was Dwayne Johnson
Can you show us an scientific, empirical and concrete evidence of his existence? The bible doesn't work because its just a fantasy book.
This is too complex for me. It must have been a god. Lol jk
congratulations ! you literally simulated the train of thoughts of every religious person !
no but really, we're joking about this but they aren't
Accurate
High school student here, at 12:14 during the Big Bang nucleosynthesis, how did they know the ratio of H:He was 3:1? I’ve googled this question and couldn’t find the explanation/answer. Was it through an experiment? Can Professor Dave or anybody help me out? Thanks :)
in one word, extrapolation
The Big Bang model makes multiple predictions, and it predicts that the ratio of hydrogen to helium should be 3:1 based on the temperature of the universe at that time, and how long fusion would've been able to occur, and this prediction was later verified after we observed that the ratio of hydrogen to helium in today's Universe is in fact 3:1
Next question, if we came out of the universe, than does that mean were the universe? Also I saw that we had the same elements as a star and everything is just right for us and animals, idk but this and philosophy are just so astonishing
Where did the 'energy' come from to cause the 'inflation' of the universe? Everyone knows that if you release gas (like hydrogen) into a vacuum (the universe) it disperses... not clump together. Gravity did not cause the stars to form. You should admit that the creation of the universe requires the 'acceptance' of several miracles (the big bang and 'inflation'). It's the law of entropy.
Um, no, they aren't miracles, you're just completely science illiterate. "Nuh uh" does not refute the entire body of astrophysics. Sorry. Learn something while you're here. And please stop pretending you know what entropy is.
@@christianredmonddales6400 Ahh you again, says the religious fanatic... The irony is crazy here.
When God snaps his finger.
THINK86200 ..."her finger". this is emanation , like a birthing. only a mother can give birth.

God has no gender. It’s a bad habit for most people cause we use Pacific pronouns, when addressing a person for saying “it” is highly offensive. But when it comes to God... we’ll it’s different. God’s Gender is just... Pregender... and over the past 2000+ years we humans had always addressed God as Male.
Me personally I see this a big part in the common controversy when it comes to God cause Human males see this pronoun we call god as “he” to say the males are superior to females when in reality we are equal.
And to say eve came from Adams rib. To say female came from male. Hence the “fe” in female as “from” as a prefix to male.
So I sense a lot of sexist controversy in the Bible when it comes to gender.
Fe; the prefix stands for the part of the word that comes before the root. So I believe it was Eve then Aden.
So I see what you’re getting at, but that’s just my theory.
@Julian Salin I believe in God and all but religion i do not entirely!
I am a man and not a feminist but in defense of some point of views.
My issue with the bible is based upon society hierarchy. those in power make history and the rules on how they want it to be. As Napoleon once said, 'What is history, but a fable agreed upon?” History is always written by the winners. who write the history books-books which glorify their own cause and disparage the conquered foe.
Men most of the time through out history were the leaders while we, am were caregivers (but not always true) of their society to shape the culture in their image of values. Henceforth making the rules and the books of their history.
In the bible God says many times in many ways on of to not changing the word of god for that is sin. Which is true and I believe that but I believe that even when the bible was being made over those many years many others altered gods word both on purpose and on accident because of how there given society was like. so men were place as the hierarchy (like calling angels and even God as “He” (but God has no gender, God is God! But that’s half fault to how english lack of use correct pronouns)
and using Gods word to say want the church to have be by taking advantage of the word to keep their ways of culture in check to never change. in some way to show how to have men always be the leader
I believe that that in the beginning God created both man and woman at the same time. Adam AND Eve (Maybe Lilith that that’s debatable)
Leaving on this to prove my point of view how I see it…
Just take a look at the Apocrypha. Yes many things about it is wrong but up to debate, the books of the Apocrypha were of writings by authors, that the churches at the time (ruled mostly by men) saw these books as not worthy, not true and just plain blasphemy. And so when it came to the book of genesis many despised the idea/ argued about who are and how they came into existence of the order in time.
I’m not saying I believe in the Apocrypha but like I said about the quote; “History is always written by the winners. who write the history books-books which glorify their own cause and disparage the conquered foe” The books of Apocrypha are like the foes who were conquered by the winner like the church. the church leaders of (mostly) men who have the final say in how they wanted things to be and or interpreted Gods word solely based on their way of life.
God gave us free will.
and what did our ancestors do? write history of a beginning to have evidence in to have defense of writing Gods word of what is true.
bit of a rant and all over the place but I hope you got the point
thanks for reading and sorry for all my overthink if so XD
Brilliant series. Thanks Prof Dave!
This is an amazingly well done video on this subject. Thank you 🙏
