Dude there are other fascinating things besides this that ancient civilizations had knowledge of that are staggering.
What reason do you have to say it comes from "God"?
Why not a time travelers?
Why not aliens?
Why not that they were more advanced than we can understand, then had a set back called religion that caused ignorance to reign?
This just sounds like more Eschatology to me, barf.
I don't see anything unique in any of this.
I could write and eschatologic prophecy and people 1000 years from now would be amazed!! These things talk about human issues and nature, its a key that fits any generation.
The Vedas also gave conflicting creation stories, and attributed gods with storms and such. Changed which god was "the greatest" and so on. Sound familiar? Religion all comes form the same toilet bowl.
