The competition is to make the story of Genesis fit some real scenario that could have happened in Earth's history. Christians maintain that the story of Adam and Eve makes allegorical sense somehow, in some way, that Christianity makes sense.
The problem with the story is that there is always something fundamentally wrong with it.
The first human is not likely to have existed, since he is identified as someone who was singular, alone and non-reproducing, and had to give birth to a woman, out of his rib cage. Supposedly, he then rejected God, and now the rest of humanity has to suffer, because we continually reject God. Can you imagine a real scenario where this is likely?
You are a man and woman in an ideal state. God comes up to you and says "This fruit will make you wise, but if you eat it, I will chuck you out of the garden, and make you and all your children suffer, with reduced lifespans, and disease. Also, when they die, I will burn them in hell for eternity." Do you tick (a) yes, I would very much like to reject God, and experience this outcome, because I'm terribly bored today, or (b) no, I'd rather not.
If a person did tick box (a), you would have to think they were terribly heroic, to brave life alone, without God, while he persecutes you, so that you can pursue a true life and develop meaning for the species. Yet, Judaism does not portray "the fall" as heroic.
Consider a civilization that existed 1 million years ago, who attained spiritual enlightenment; say Atlantis, or the Silurians. Most likely, they would want to keep that hard-won state, just as we would want to keep democracy and freedom of speech. And yet, the Bible says that we fell from that state, because we were conned into eating a magic fruit, that made us wise. Now, I could imagine this being possible if the magic fruit was an all-you-can-eat sex buffet, that made you stupid. That would explain a lot. I can imagine man falling, because he was tempted by something, well, ... tempting. But, no, the Bible says humans were tempted by WISDOM, and that we existed in a virginal primal state, where we knew no evil, sin, or reproduction. This ideal state consisted of doing nothing: not even playing WoW. Notice how the Bible makes no mention of what Adam was doing for employment.
The Bible then deals, for a good zero verses, on what Adam was doing with himself, prior to the serpent coming along, and screwing it all up. This is how well God designed A&E, to withstand "temptation" for about 1 day. It was so shit boring, that the most interesting show in town, was a talking snake, who was selling something that neither of them wanted.
Then, God turns us out of our paradise, because he feared us eating from another strange tree, which would surprisingly give us true immortality. It's difficult to think of a real life scenario, where God(s) or we, would leave a tree like this lying around, or it was a tree that we hadn't already eaten from. The tree of life seems irrelevant to the story. It's also strange that God didn't want Adam and Eve to become Gods, like "us". No explanation is given. The underlying assumption is that Adam and Eve weren't good enough for it, even though they would have been "one of us", and have no magical powers, to create universes. Apparently, God loved Adam and Eve so much, that he didn't want to provide work experience training, to rehabilitate them.
There have been a few attempts in sci-fi, to imagine how a civilization could attain an innocent state. If they had forgotten all wisdom, then the civilization could be easily disturbed, by any outside force. But then, in this virginal civilization, there would be more than one man. So, something had already gone terribly wrong, if a perfect civilization reduced itself to one stupid man, who knew nothing, and did nothing.
I can't see how the story in Genesis is analogous to anything that could have existed, or was likely to have happened, even if it didn't exist. If it was an Indy movie, it would be reviewed on IMDB as:
1 Star. Really dumb story. I can't beleive god woudl do any of that shit.
1 Star. I would ahve given it zero, but there is no option for that.
1 Star. They didn't even have sex, How dumb is that? I don't think Brad Pitt was a good choise for Adam, even though he tried to bring the script alive, it was DOA. That was 2 hours I'll never get back.
1 Star. I'm giving it 1 star for the snake. The CGI on that was cool, but God looked a little stupid. Brad would have been better as God.
