Moses wrote the first five books of the bible... I suggest to you that there is absolutely no way whatsoever, nor is their any reason at all, for him to "make it up" even considering "if" he could possibly have "made it up. So this leaves only one possibility, and that is these "stories" were designed and "told" to us for a Divine, or possibly "alien" (if you want to use that term) "purpose" and design... "It", these "stories" were designed and told to us by a "higher" "intelligence" for a specific "reason" and a "purpose"...
Now, I believe it is our "Job" as "truth seekers" to "seek out" what these "reasons" and "purposes" were/are, whether the "stories" are "literally" true, or maybe just "subjectively" true, which is what I believe, (that they are "subjectively" true) that they (these stories) alude to some kind of "higher purpose" of maybe (perhaps) unique revelations and deep understandings of our own human behavior (psychology) human nature, and to (I believe) give us a fighting chance of "becoming" something "more" than just "primates" or animals.
Anyways, that's what I believe, you can and are free to "choose" whatever you want to choose to believe...
In the popular movie the Matrix series the commander of the armies says to Morpheous, "Morpheous, not everyone believes what you believe" and Morpheous response is "My beliefs do not require them to" and that's exactly how I feel, so believe (or don't) whatever you want, but I know what I believe and I do not "require" you to agree with me in order to believe it.
I'm Just saying that there are just so, so many "open" Possibilities and I am only suggesting to you only a few that I can think of, that I just wish people would retain an "open" (and not closed) mind about things especially when it comes to God, or things that were obviously "presented" to or "infused" into our culture by a "higher" intelligence and "ponder" the reasons why...
You see, "proof" doesn't even matter at this point either way, because these stories have predestined the way in which our society would go, "evolve" for ages, and even if you, for example could somehow "prove" (And I don't believe you can, but one can most certainly "try") Somehow, "Prove" that these stories were "made-up" somehow, (And, I gaurantee that if they were, it was not by men), but my point is these stories, are a bit like "seed" codes in our DNA, that have directed when and where our society would "be" up to this point, the real question we should be asking ourselves is "why"? Why have we been brought to this "point"
I'm Going to use a Matrix analogy again, In the Movie "Matrix" the Oracle has a conversation with Neo, and she says to him, (at one point in their conversation) "Oh, and don't worry about the vase" and then Neo turns and starts to say something like "What vase?" but as he's turning around and about to finish saying it, he knocks over the vase and it falls to the floor and breaks, and He (Neo) starts to say something like "I'm sorry" but/and she tells him "I said, don't worry about it" and then she says something very relevant to our conversation here, she says "What's really going to "boggle" your noodle later on is, would you still have broken it if I hadn't said anything"
And that's kinda the way it is with us, everything that's been said (in the bible for example) has directed us (to a certain degree) to this point in our history, and it's the "now" and "why" and "how" that we should "concern" ourselves with, nothing else (really) matters
My Prayers be with you all, thanks for listening, Jay.
