So what? You do realize Babylon was founded decades after the tower of Babel!? Babel was after the flood! ha.
"The year was 331 BC. After Alexander the Great had defeated Darius at Gaugmela near Arbela, he journeyed to Babylon. Here he received 1903 years of astronomical observations from the Chaldeans, which they claimed dated back to the
founding of Babylon. If this was so, then that would place the founding of Babylon in 2234 BC, or about
thirteen years after the birth of Peleg. This was recorded in the sixth book of
De Caelo (“About the heavens”) by Simplicius, a Latin writer in the 6th century AD. Porphyry (an anti-Christian Greek philosopher, c. 234–305 AD) also deduced the same number.

In the Days of Peleg
Apparently it is likely that Peleg was about 5 years old at the time of Babel. (it was also in the days of Peleg, incidentally that the world was divided) That would place the founding of Babylon around 8 years after Babel!!!!!!!
