What is the oldest civilization on Earth?
Wow, I had no idea. Thanks for sharing that information with me. Is there anything else you can tell me about ancient Sumer?
Ancient Sumer was a polytheistic civilization, with a complex religious pantheon that included deities such as Anu, Enki, and Inanna. They also had a highly stratified social structure, with priests and rulers at the top and slaves at the bottom. The civilization ultimately declined and fell around 2000 BCE, due to a combination of factors such as foreign invasions, droughts, and political upheaval.
