An origin myth is a myth that purports to describe the origin of some feature of the natural or social world. One type of origin myth is the cosmogonic myth, which describes the creation of the world. However, many cultures have stories set after the cosmogonic myth, which describe the origin of natural phenomena and human institutions within a preexisting universe.

A creation myth is a symbolic narrative of how the world began and how people first came to inhabit it. While in popular usage the term myth often refers to false or fanciful stories, formally, it does not imply falsehood. Cultures generally regard their creation myths as true. In the society in which it is told, a creation myth is usually regarded as conveying profound truths, metaphorically, symbolically and sometimes in a historical or literal sense. They are commonly, although not always, considered cosmogonical myths—that is, they describe the ordering of the cosmos from a state of chaos or amorphousness.
