What religion did the sumerians believe in?

Answer 1

The Sumerians believed that the world was created out of an an ancient sea from whence the universe, gods, and people were created. They believed that the universe was ruled by these gods, who were anthropomorphic (they had human features and personalities) and who represented various natural phenomenon. Each Sumerian city-state had its own patron deity to whom the citizens paid homage. Temples, known as ziggurats, were often erected in the cities to honor and house each city's god. The city of Ur, for example, constructed a ziggurat for Nanna, the god of the moon.

The key gods of the Sumerians were Enki (god of water), Ki (god of earth), Enlil (god of air), and An (god of heaven). These main gods were believed to have created the rules of Sumerian society to which all people were expected to adhere. Sumerians also believed that the reason for their existence was to delight the gods. The observance of certain rituals and animal sacrifices were considered necessary in order to satisfy these often capricious deities.
