One form of mythology was based on the most visible of the heavenly bodies. In some cultures they were considered the eyes of a Supreme Being. Myths of human descent from a sun-god are known among some North American Indian tribes, including the Arapaho and Blackfeet. They are also common in Indonesia and Melanesia. Ruling dynasties in Egypt, Korea, and Japan have also claimed descent from the sun. The moon?because it appears, disappears, and appears again?was believed by some peoples to be the first human who died. In some cases the moon god was viewed as one who had taken the place of a Supreme Being.
