The Nyamwezi people of Tanzania in East Africa worship Mulungu as the god who created all things and who watches over the earth. Although he created the world, Mulungu is a very distant god with no personal relationship with living beings.
According to legend, Mulungu once lived on earth. He left and went to live in heaven because some people set fire to the landscape, causing devastation and killing many other people. Unable to climb the tree that linked heaven and earth, Mulungu asked Spider to help him travel up to the sky. Spider climbed up, spun a thread, and let one end of the thread fall to earth. Mulungu followed the thread up to heaven.
