Ra was thought to be the god of the sun and creation. Ra’s name came from Re and Amun. The name Re was from Upper Egypt and the name Amun came from Lower Egypt. When Upper and Lower Egypt came together they changed the name to Amun-Re. Over thousands of years the name Amun-Re evolved into Amun-Ra and then just to Ra. From then on people called him Re or Ra. Ra used to mean “mouth” in the Egyptian language. Some names are: Re, the Creator, Khepry, etc.
