Actually, he worships Rao.
Rao is the first being to be born out of the void before the universe. Feeling lonely, he sought to bring order to the chaos from which he was born, and thus created the universe. After countless eons of ordering the cosmos, Rao created Krypton, a planet meant to be a jewel in his creation. Rao then created all the other Kryptonian gods from his own essence, and these godlings called him "Father Rao". Rao, in the time just before and after the destruction of Krypton, is thought of by the people of Krypton like God in Abrahamic Religions. He is all knowing, all powerful and eternal. He is served by his minor gods, who could be better understood as his angels. Each minor god is worshiped by a guild or caste on Krypton while all people worshiped Rao.
