Is Lord Vishnu the son of Aditi and Kashyapa

Is Lord Vishnu the son of Aditi and Kashyapa and the younger brother of Indra? Supreme Lord Vishnu is eternal and without beginning. However pleased with the devotion of Aditi, he incarnated as her son. Because of this he is called the younger brother of Indra or Upendra. In days gone by, the illustrious Vishnu was worshipped by Aditi with great austerities; and he then, pleased with Aditi, bestowed a boon on her. " I desire to have you as a son." This your mother Aditi spoke to the god Narayana and after having offered him prayers she bowed down to him. Thereupon she was told by him "There is no person equal to myself in the universe; I shall therefore be born as your son in my own parts. Thus, O lord of the celestials, that creator of all, the highly powerful Narayana, was born as your brother and he is called Upendra. Thus out of his own will did that lord of the past, present and future, the eternal god Hari, create himself in the race of the Kasyapa, because it is in his nature to incarnate himself in this wise.
