When was the Mesopotamian city of Babylon first established?
Wikpedia: The earliest source to mention Babylon may be a dated tablet of the reign of Sargon of Akkad (ca. 24th century BC short chr.). The so-called “Weidner Chronicle” states that it was Sargon himself who built Babylon “in front of Akkad” (ABC 19:51). Another chronicle likewise states that Sargon “dug up the dirt of the pit of Babylon, and made a counterpart of Babylon next to Agade.” (ABC 20:18-19). ============ But the city may have been much older than that. It has been equated with the “Babel” of Genesis 10 (which relates a story much older than when it was first written down c 2000 BC) and other scholars link it with Eridu, which was founded c 4000 BC.
