Egyptian astronomy was closely linked to their agricultural calendar and religious practices. The ancient Egyptians observed the night sky to track the movements of celestial bodies, particularly the Sun, Moon, and stars. They used these observations to create a calendar that helped them predict the annual flooding of the Nile River, which was crucial for farming. The Egyptians also built monumental structures, such as the Great Pyramids and the Temple of Karnak, aligned with specific stars and solar events. Their knowledge of astronomy influenced their architecture and rituals, reflecting the importance of the cosmos in their daily lives and beliefs.
