Kashyapa is the first of the Saptarishi list. According to the cosmogonic myth set forth in the Shatapatha Brahmana, Prajapati created all living things, incarnating in a cosmic turtle. This turtle is Kashyapa, therefore it is said that all living entities are descendants of Kasyapa.
He is the husband of Aditi, the father of many gods, for example, the Adityas (suns). He is also the ancestor father of the Asura dynasty, who were born from his other wife, Diti, and are called Daitya. In Hindu mythology, Kashyapa is the son of Brahma or an emanation of Marichi (the spirit of Brahma - Prajapati). The eight daughters of Daksha are also considered the wives of Kashyapa.
From Diti he had sons Daityas, from Danu - Danavas, from Aditi - thirty-three gods, his other wives gave birth to Gandharvas, Apsaras, Nagas, Rakshasas, animals and other creatures. The grandson of Kasyapa from his son Vaivasvata Manu became the progenitor of people. As the father of gods and asuras, humans and demons, snakes and birds, Kashyapa symbolizes the primordial unity that precedes the dualism of creation.
In a number of texts, Kashyapa is identified with Prajapati or Brahma
