From Wiki "Egyptians recognized that the Pharaoh was human, they simultaneously viewed him as a god, because the divine power of kingship was incarnated in him. He therefore acted as intermediary between Egypt's people and the gods. The Egyptians believed that humans possessed a life-force, which left the body at the point of death. It was believed that, to endure after death, the spirit must continue to receive offerings of food, whose spiritual essence it could still consume."
