Final answer:
Monotheism is the belief in one deity, while polytheism is the belief in multiple deities.
Step-by-step explanation:
Monotheism is the belief in the existence of only one deity. It is commonly associated with religions like Judaism, Christianity, and Islam, which all believe in the worship of a single, omnipotent God.
Polytheism, on the other hand, is the belief in the existence of multiple deities. This concept is found in religions like Hinduism, ancient Greek and Roman religions, where worship is directed towards many gods and goddesses.
So, the key difference between monotheism and polytheism lies in how many deities are worshipped.
