Mbh 12.166.4a

"'Bhishma said, "Hear the truth, O son of Madri, about what thou hast asked me. I am excited by this question of thine, like a hill of red-chalk.[480] In ancient times the universe was one vast expanse of water, motionless and skyless, and without this earth occupying any space in it. Enveloped in darkness, and intangible, its aspect was exceedingly awful. Utter silence reigning all over, it was immeasurable in extent. In his own proper time the Grandsire (of the universe) took his birth. He then created the wind and fire, and the sun also of great energy. He also created the sky, the heavens, the nether regions, earth, the directions, the firmament with the moon and the stars, the constellations, the planets, the year, the seasons, the months, the two fortnights (lighted and dark) and the smaller divisions of time. The divine Grandsire then, assuming a visible form, begot (by power of his will) some sons possessed of great energy. They are the sages Marichi, Atri, Pulastya, Pulaha, Kratu, Vasishtha, Angiras, and the mighty and puissant lord Rudra, and Prachetas. The last begat Daksha, who in his turn, begat sixty daughters. All those daughters were taken by regenerate sages for the object of begetting children upon them. From them sprang all the creatures of the universe, including the gods, Pitris, Gandharvas, Apsaras, diverse kinds of Rakshasas, birds and animals and fishes, monkeys, great snakes, and diverse species of fowl that range the air or sport on the water, and vegetables, and all beings that are oviparous or viviparous or born of filth. In this way the whole universe consisting of mobile and immobile creatures sprang into existence. The universal Grandsire, having thus evoked into existence all mobile and immobile creatures, then promulgated the eternal religion laid down in the Vedas.
