In 331 BC after Alexander the Great had defeated Persian King 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.
8Now Cush fathered Nimrod; he [d]became a mighty one on the earth. 9He was a mighty hunter before YHVH; therefore it is said, “Like Nimrod a mighty hunter before YHVH.” 10And the beginning of his kingdom was [e]Babel, Erech, Accad, and Calneh, in the land of Shinar.11From that land he went to Assyria, and built Nineveh, Rehoboth-Ir, Calah, 12and Resen between Nineveh and Calah; that is the great city. 13Mizraim fathered Ludim, Anamim, Lehabim, Naphtuhim, 14Pathrusim, Casluhim (from whom came the Philistines), and Caphtorim.
Genesis 10:8-14
Nimrod was the 4th generation from Noah through Ham. Many places retained their ancient Sumerian names as well as their contemporary Akkadian names. Babylon – BAB-ILU ib Akkadian was also identified by its Sumerian name NUN.KI nun (Sumerian) = rubum (Akkadian) meaning ‘mighty’. kar (Sumerian) = habilum (Akkadian) meaning ‘hunter’. The city of Nun.ki ‘mighty place’ is otherwise known as Eridu.
2. Now it was Nimrod who excited them to such an affront and contempt of God. He was the grand-son of Ham, the son of Noah: a bold man, and of great strength of hand. He persuaded them not to ascribe it to God, as if it was through his means that they were happy; but to believe that it was their own courage which procured that happiness. He also gradually changed the government into tyranny; seeing no other way of turning men from the fear of God, but to bring them into a constant dependence on his own power. He also said, “He would be revenged on God, if he should have a mind to drown the world again: for that he would build a Tower too high for the waters to be able to reach; and that he would avenge himself on God for destroying their fore-fathers.”
