The ancient Egyptians believed in many gods and goddesses, each with their own role in maintaining harmony. Some major deities included Ra, the sun god; Osiris, god of the underworld; Horus, protector of pharaohs; Seth, god of chaos; Isis, mother goddess; and Thoth, god of wisdom. Lesser gods were associated with nature, towns, animals, and other domains. The Egyptians saw it as important to worship these gods through rituals and offerings to keep the world functioning properly.
