Was it even real?
Odds that it actually existed are about the same as the odds that a a group of 2-3 million people wandering about in the desert for 40 years left not a trace that they had ever been there.
Or the odds that that the entire earth was covered by water 4400 years ago.
Or the odds that everyone on the planet spoke the same language until about 4200 years ago.
Or the odds that the Assyrian empire was able to muster up, train, feed, and arm an army of 185,000 men, let alone that all 185,000 died in one night.
Or the odds that an bronze age Ethopian army numbered 1 million men.
Or the odds...well you get the picture.
