Mind-blowing timeline! Uruk's foundations reach back to ~5000 BC, and it's where cuneiform was invented around 3100 BC — later spreading to Akkadians, Babylonians, Assyrians, and Persians. Sumerians considered nearby Eridu (~5400 BC) the first city, established by the god Enki. Remarkably, Sumerian texts were still being copied when Alexander died at Babylon in 323 BC!
