Hinduism includes a range of viewpoints about the origin of life, creationism and evolution. The Rigveda mentions the Hiranyagarbha ("golden embryo") as the source of the creation of the Universe, similar to the world egg motif found in the creation myths of many other civilizations. It also contains a myth of proto-Indo-European origin, in which the creation arises out of the dismemberment of a cosmic being (the Purusha) who is sacrificed by the gods. As for the creation of the primordial gods themselves, the Nasadiya Sukta of Rigveda takes a near-agnostic stand, stating that the Gods came into being after the world's creation, and nobody knows when the world first came into being. In the later Puranic texts, the creator god Brahma is described as performing the act of 'creation', or more specifically of 'propagating life within the universe'. Some texts consider him equivalent to the Hiranyagarbha or the Purusha, while others state that he arose out of these. Brahma is a part of the trinity of gods that also includes Vishnu and Shiva, who are responsible for 'preservation' and 'destruction' (of the universe) respectively.
Many Hindu texts mention the cycle of creation and destruction. The Shatapatha Brahmana states that the current human generation descends from Manu, the only man who survived a great deluge after being warned by the God. This legend is comparable to the other flood legends, such as the story of the Noah's Ark mentioned in the Bible and the Quran.
