The primordial being in Mesopotamian mythology is Apsu, often associated with the waters of chaos. Apsu is a male deity representing the primeval ocean, who, alongside Tiāmat, signifies the elemental forces of creation. Together, they gave rise to the gods and the world as known in the Enuma Elish creation myth. Their relationship illustrates the ancient understanding of the universe’s origins, anchored in the tension between order and chaos.
