When there was nothing but Nun the dark waters of chaos. Ben-ben arose from the waters as hill. Then Ra came, he was the first god. Next Ra coughed up Shu god of air and Tefnut goddess of moisture. The two of them had two children. Geb the god of the earth and then Nut goddess of the sky. So then, Shu lifted up Nut to become the canopy over Geb. While the earth rotates Ra takes a journey around the earth and when he goes to the dark side when the moon was up they would think that he was going through the underworld. So the Egyptian prayed for Ra as he made his journey.
