When the world was first created, each god had a specific job to help maintain the land. But being fresh off the boat of creation, the gods were not used to hard labor; so, like any adolescent god, they complained, demanding help.
Tired of hearing the constant whining, one day the water goddess Nammu, birth mother of heaven and earth, decided to create man to help care for the land. She assigned Enki—the patron of all arts, crafts, wisdom and magic, and Ninmah—the Great Mother goddess and Enki´s feisty lover—the creation task.
But like happens with teenagers, the two creator gods got drunk before beginning the job. The idea was that Ninmah was to create beings out of clay, while Enki found a role for each creation. Imagine doing surgery while drunk. Well, the first creation was completely un-viable, unable to stand or feed itself, and had to be held in Ninmah’s lap.
And thus, by the hands of drunken gods, was born the first human infant.
