Mesopotamian mythology is the collective name given to Sumerian, Akkadian, Assyrian, and Babylonian mythologies from parts of the fertile crescent, the land between the Tigris and Euphrates rivers in the Zagros mountains. The Sumerians practiced a polytheistic religion, with anthropomorphic gods or goddesses representing forces or presences in the world, in much the same way as later Greek mythology. According to said mythology, the gods originally created humans as servants and freed them when they became too much to handle.
