Brahmanas
The Shatapatha Brahmana mentions a story of creation, in which the Prajapati performs tapas to reproduce himself. He releases the waters and enters them in the form of an egg that evolves into the cosmos. The Prajapati emerged from the golden egg, and created the earth, the middle regions and the sky. With further tapas, he created the devas. He also created the asuras, and the darkness came into the being. It also contains a story similar to the other great flood stories, such as the one mentioned in the Bible. After the great flood, Manu the only surviving human, offers a sacrifice from which Ida is born. From her, the existing human race comes into the being.
