One Ancient Egyptian origin myth relates that in the beginning, the universe was filled with the dark waters of chaos. The first god, Re-Atum, also Ra-Atum appeared from the Water as the land of Egypt appears every year out of the flood waters of the Nile. Re-Atum spat and out of the spittle came out the deities Shu (air) and Tefnut (moisture). The world was created when Shu and Tefnut gave birth to two children: Nut (Sky) and Geb (the Earth). Humans were created when Shu and Tefnut went wandering in the dark wastes and got lost. Re-Atum sent his eye to find them. On reuniting, his tears of joy turned into people.
