Mungu is the creator god.
The earth and the sky were once one, until Mungu put the sky above and the earth below. God also made a small human child, and he told him to remain there. The boy grew up. Then God began to search, saying that he wanted to find someone to live with the man. He killed that man, and took out one of his ribs, from which he made a girl who grew up and bore children. God asked them why they bore children. The man said that he did not know that God had forbade them to have children. God said, “I have given you death and health.” And he said, “Go.”
