Myth is a folklore genre consisting of narratives that play a fundamental role in a society, such as foundational tales or origin myths. The main characters in myths are usually non-humans, such as gods, demigods, and other supernatural figures. However, others also include humans, animals, or combinations in their classificiation of myth. Stories of everyday human beings, although often of leaders of some type, are usually contained in legends, as opposed to myths. Myths are sometimes distinguished from legends in that myths deal with gods, usually have no historical basis, and are set in a world of the remote past, very different from that of the present.
Myths are often endorsed by rulers and priests or priestesses and are closely linked to religion or spirituality. Many societies group their myths, legends, and history together, considering myths and legends to be true accounts of their remote past. In particular, creation myths take place in a primordial age when the world had not achieved its later form. Other myths explain how a society's customs, institutions, and taboos were established and sanctified.
