What do you call individuals who worship and believe in many Gods?

Individuals who worship and believe in many gods are referred to as polytheists. This term is derived from the Greek words "poly," meaning many, and "theos," meaning gods. Polytheism is a belief system commonly found in various cultures throughout history, where multiple deities are acknowledged, each with specific roles, attributes, and influences over different aspects of life and the universe.

Monotheists, on the other hand, believe in and worship a single god, while atheists deny the existence of any gods. Agnostics hold a position of uncertainty regarding the existence of gods, typically stating that it is unknown or unknowable. Therefore, polytheism distinctly characterizes the belief in numerous gods, making it the correct choice for this question.
