Ancient Egyptians believed in a complex system of gods and goddesses, each representing different aspects of life and nature. Key deities included Ra, the sun god, and Osiris, the god of the afterlife. They thought that these gods influenced daily life and the afterlife, leading to a strong emphasis on rituals and offerings to gain favor. The concept of the afterlife was central to their beliefs. Egyptians believed that the soul, or ka, would continue to exist after death. To ensure a safe passage to the afterlife, they practiced mummification and built elaborate tombs, such as the pyramids, to house the deceased and their belongings.
