Polytheism is the belief in and worship of multiple gods or deities. This religious practice is common in various cultures and can be seen in ancient civilizations such as the Greeks, Romans, and Egyptians. Each god often represents different aspects of life, such as love, war, or nature, and may have unique stories and attributes. In polytheistic religions, rituals and offerings are typically made to honor these gods, seeking their favor or assistance. Examples of polytheistic belief systems include Hinduism, which features a vast array of deities, and the ancient Norse religion, which worshipped gods like Odin and Thor.
