Atum

Atum was an important deity from Egyptian mythology, who was often seen as the creator of the world.

Overview
According to the creation story of Heliopolis, Atum originated from the water of Nun, being the first of the gods and the progenitor of all other deities. He sired the gods Shu and Tefnut, who became the gods of wind and rain. At some point Atum got separated from his children, but eventually found them again, which led him to cry in joy and the tears would become the first humans.

Atum and his children would continued to expand the universe, with Shu and Tefnut having children of their own, Geb and Nut, who were the land and the sky. These two then sired the next generation of deities: Osiris, Isis, Nephthys and Set, who ruled over the humans as the first royal family.

He would later be seen as just the human-incarnation of the sun-god Ra.
