Native American cultures are numerous and diverse. Though some neighboring cultures hold similar beliefs, others can be quite different from one another. The most common myths are the creation myths, that tell a story to explain how the earth was formed, and where humans and other beings came from. Others may include explanations about the sun, moon, constellations, specific animals, seasons, and weather. This is one of the ways that many tribes have kept, and continue to keep, their cultures alive; these stories are not told simply for entertainment, but as a way of preserving and transmitting the nation, tribe, or band's particular beliefs, history, customs, spirituality, and traditional way of life. "tories not only entertain but also embody Native behavioral and ethical values."
