Enûma Eliš
The ancient Sumerian myth of "Enûma Eliš", inscribed on cuneiform tablets and part of the Library of Ashurbanipal, says humankind was created to serve gods called the "Annunaki". Hypothesis proponents believe that the Annunaki were aliens who came to earth to mine gold for their own uses. According to the Enuma Elish story, the Annunaki realized mining gold was taking a toll on their race, and then created the human race as slaves.
