> God destroyed it

Where does it say that? I have never read any Book of Genesis that says "God destroyed the tower".

Also it doesn't say "God was afraid". God doesn't have negative emotions like that. God plans out everything, so He is not "afraid" in the human sense.

In fact, I am fairly certain that the mythical "Tower" for the Jews was sort of a parody of the Pyramids of Egypt and the Ziggurats of Mesopotamia. They were essentially mocking their ancient neighbors in the Levant for such a frivolous project that they believed really didn't honor God, but increased their arrogance and hubris.

In fact, the Sumerians worshipped a god named "Sin" https://en.wikipedia.org/wiki/Sin_(mythology) and it is believed that the "plain of Shinar" and the "wilderness of Sin" are cognate with this term, and therefore represents the ancient deity that was worshipped in that particular case.

For Egypt, the pyramids were funerary monuments, i.e. they invariably honored some dead Pharaoh. The Jews invested their engineering progress in building a temple of the Living God instead.

So it stands to reason, in the Hebrews' account of the foreign projects, that immigrants would come in, mess up the project enough, and they would kinda abandon them in progress. But they weren't destroyed.

Douglas Adams's prediction seems more apposite:

"Meanwhile, the poor Babel fish, by effectively removing all barriers to communication between different races and cultures, has caused more and bloodier wars than anything else in the history of creation."

But almost everyone speaks English as a second language, and most native English speakers don’t care enough to communicate with everyone.
