Egyptian religion was a complex system of beliefs and practices centered around a pantheon of gods and goddesses, such as Ra, Isis, and Osiris. The ancient Egyptians believed these deities controlled various aspects of life and nature, including the sun, fertility, and the afterlife. Temples were built to honor these gods, and rituals were performed to ensure their favor. The afterlife was a significant focus in Egyptian religion, with the belief that the soul would be judged by Osiris after death. The Book of the Dead served as a guide for the deceased, outlining spells and instructions for navigating the afterlife. This belief led to elaborate burial practices, including mummification and the construction of tombs.
