The earliest record of the Sumerian creation myth, called The Eridu Genesis by historian Thorkild Jacobsen, is found on a single fragmentary tablet excavated in Nippur. It is written in the Sumerian language and dated to around 1600 BC. Other Sumerian creation myths from around this date are called the Barton Cylinder, the Debate between sheep and grain and the Debate between Winter and Summer, also found at Nippur.
Where the tablet picks up, the gods An, Enlil, Enki and Ninhursanga create the black-headed people and create comfortable conditions for the animals to live and procreate. Then kingship descends from heaven and the first cities are founded: Eridu, Bad-tibira, Larak, Sippar, and Shuruppak.
After a missing section in the tablet, we learn that the gods have decided not to save mankind from an impending flood. Zi-ud-sura, the king and gudug priest, learns of this. In the later Akkadian version, Ea, or Enki in Sumerian, the god of the waters, warns the hero (Atra-hasis in this case) and gives him instructions for the ark. This is missing in the Sumerian fragment, but a mention of Enki taking counsel with himself suggests that this is Enki's role in the Sumerian version as well.
