Creation myths are narratives that seek to explain fundamental questions about existence through imagined supernatural accounts of how the world and human beliefs/practices originated. There are five main types of creation myths: ex nihilo where a deity creates from nothing; chaos myths involving a breaking of primordial chaos; earth diver myths where a being retrieves land from waters; emergence myths of gradual creation through multiple worlds; and world parent myths of separated primal pairs or a parent's dismemberment creating the cosmos. Myths serve important religious and cultural functions by establishing an axis mundi and affirming a society's values in relation to first principles.
