The sun god Ra is one of the most important deities in ancient Egyptian mythology. He is often depicted with a falcon head and a sun disk above it, symbolizing his role as the god of the sun. Ra was believed to travel across the sky in a solar boat during the day and journey through the underworld at night, representing the cycle of life and death. Ra was associated with creation and was considered the father of many other gods, including Osiris and Isis. Worship of Ra was widespread, and he was often linked to the pharaohs, who were seen as his earthly representatives. Temples dedicated to Ra were built throughout ancient Egypt, emphasizing his significance in their culture.
