Saul Shanjfeld asks RYGB, concerning a literal understanding of the Noach story:
And how did Noach's sons, who knew how to make metal, read and write literature, evolve into illiterate bushmen with bones through their noses who beat on tree stumps?
The answer is poshut! When everyone magically flew through the air to the various regions of the world after the Tower of Bavel incident, the tremendous air pressure and g-forces caused them to forget everything they once knew, and they turned into ignorant bushmen. Or maybe it was kinda like a Blue Lagoon or Castaway situation - one or two people got sent to a remote location and they didn't have the smarts to pass on reading or writing to their kids. Or maybe they had kids but then they died shortly after that and so the kids were not educated. Or maybe the kids were the ones who were transported to the remote locations, and then they didn't have the education to begin with. See, it's not such a kashye at all! Either that, or it was a nes that Hashem specifically created to test our emunah.
And if you believe any of that, you need your head examined.
