Documented in the Atrahasis epic (Old Babylonian, c. 18th century BC): the junior gods, the Igigi, refuse the labor; Enki and the mother goddess fashion workers from clay mixed with a slain god's flesh; humanity multiplies; Enlil, afflicted by the noise, sends plague, drought, then the flood; Enki warns Atrahasis, who survives in a boat. Enlil and Enki are likewise the paired authority-and-craft poles across Sumerian literature, Enlil decreeing fates at Nippur, Enki holding the me, the arts of civilization, at Eridu.
The folk synthesis, Wallis's and the ancient-astronaut circuit's: Enlil and Enki as rival administrators, one for the labor program's containment, one for its uplift, their quarrel over human consciousness and freedom echoed in the serpent-versus-commander structure of Eden, where the serpent's crime is Enki's: unauthorized knowledge transfer.
The claim, the gnostic retrofit: Enlil is the Demiurge's local prefect, Enki the serpent of the Apocryphon, the flood as the wardens' reset and the boat as the first documented jailbreak. The King List's handover after the flood reads, on this account, as the prison's administrative reform.
