The creator god of the Salish is Amotken, a kind, elderly man who lives alone in heaven. He created five women from five hairs from his head and asked them what they wanted to be. Each gave him a different answer: wickedness and cruelty, goodness, mother of the Earth, fire, water. Amotken did as they asked and declared that wickedness would rule Earth for a time, but goodness would win in the end.
Tsauz was a crippled boy who was very ugly. In many different variations on the same story, Tsauz became strong and beautiful.
Mythology figures prominently in most religions, and most mythology is tied to at least one religion.
Stories from scripture are usually not referred to as mythology except in a pejorative sense, but one can speak of a Jewish mythology, a Christian mythology, or an Islamic mythology, in which one describes the mythic elements within these faiths without speaking to the veracity of the faith's tenets or claims about its history.
Mythology is alive and well in the modern age through urban legends, scientific mythology, and many other ways.
