Answer:
True. The sumerians were polytheistic.
Step-by-step explanation:
Polytheism is a religious or philosophical conception based on the existence of various divine beings or gods. The Sumerians originally practiced a polytheistic religion with anthropomorphic deities that represented the cosmic and terrestrial forces in their world.
The Sumerians imagined the universe as a closed dome surrounded by a sea of salt water. The base of the dome was formed by a land layer, there was an underworld and an ocean of fresh water called the Kur. The deity of the firmament of the dome was called An, and that of the earth, Ki. Enlil was born from the primordial union between An and Ki, and became the supreme god of the Sumerian pantheon.
According to the Sumerian mythology of creation, the gods originally created humans to serve them, as they needed to be fed and clothed. The cult was thus conceived as a way of serving the gods.
