"Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth."
Genesis 11:9 KJV
Humans erected a tower to more closely observe the Gods: The planets. Their movements had damaged the earth and foreknowledge was regarded as vital. So observation buildings were constructed.
"And they said, Go to, let us build us a city and a tower, whose top [may reach] unto heaven; "
Genesis 11:4 KJV
What happens once in nature frequently happens recurrently. Lightning often strikes the same place over and over again. Planetary orbits are predictable. The planet that came close to earth, the LORD, then loosed charge across thousands of miles, called a thunderbolt by the Greeks. This thunderbolt was accompanied by thunder, being the immediate and explosive expansion of air. The air pressure of modern bombs kills by compression of body organs, literally crushing the life out of the victims. Those further away are rendered permanently deaf.
Deafness was planet wide after the series of close planetary encounters! The survivors were able to reproduce, but their written and oral languages were useless: they could not teach their hearing children. Imagine the sadness of the loss of culture! No songs, no stories. Their children were condemned to begin another culture, based upon the old one. The generations were forever separated.
