Human: When did the first monotheistic religions appear? Assistant: 
The first monotheistic religions appeared in the Middle East around 3,000 BCE. This is when the Sumerians and Babylonians adopted the idea of a single god who was the creator of the universe. They believed that the god was the source of life and death, and that he had created everything in the universe. The Hebrews adopted this belief system and made it their own.
