Atum

Atum, sometimes rendered as Atem, Temu, or Tem, is the primordial God in Egyptian mythology from whom all else arose. He created himself and is the father of Shu and Tefnut, the divine couple, who are the ancestors of the other Egyptian deities. Atum is also closely associated with the evening sun. As a primordial god and as the evening sun, Atum has chthonic and underworld connections. Atum was relevant to the ancient Egyptians throughout most of Egypt's history. He is believed to have been present in ideology as early as predynastic times, becoming even more prevalent during the Old Kingdom and continuing to be worshiped through the Middle and New Kingdom, though he becomes overshadowed by Ra around this time.
