Speculation me thinks...The Torah is a compilation of the oral traditions of the 12 tribes of Israel. These people had zero scientific understanding of the world around them and were very primitive. Look at it this way, they were desert nomads. Do you hold any stock in the mythology of present-day desert nomads? I think the story of the temple of Babble was just a way to explain why people speak different languages. The most likely explanation is that the Babylonians used slaves from all over their empire to build the tower. That would have put all different types of people speaking all different types of languages close together in one locale. Bible historians think that at the time the Israelis came up with this story, they weren't even aware of the existence of Europeans or Asians or Native Americans or Indians. Their global outlook would have been very narrow and localized.
No condescension intended.
