it never happened! the creator of this spurious tale didn't understand that language changes occur when people leave an area, not when some hebrew god confuses their tongues to make them leave! this thing was never built by anyone for the stated purposes to which this tale relates. it's a total fiction or a skillful lie. after all, babylon wasn't around when it was spawned. but, a curious thing happened - a king's library was found and some of it was translated, exposing the hebrew author's lies about babylon.
