In Incan mythology, Viracocha was the creator of the world and humanity, and one of the most important deities. He was a sun god and a storm god. He had one son: Inti; and one daughter: Mama Quilla. His wife was Mama Cocha.
He destroyed the giants (before mankind existed) with a Great Flood called Ono pacakoti, saving two to help repopulate the globe.
