Ra is the ancient Egyptian god of the sun, often considered one of the most important deities in Egyptian mythology. He is usually depicted with a falcon head and a sun disk above it, symbolizing his role as the giver of light and life. Each day, Ra is believed to travel across the sky in his solar boat, bringing warmth and illumination to the world. At night, Ra descends into the underworld, where he battles the serpent Apep, representing chaos and darkness. This daily journey symbolizes the cycle of life, death, and rebirth, highlighting the Egyptians' deep connection to the sun and its vital role in sustaining life on Earth.
