A myth is a story about the remote past which is considered true within the society in which it is told. Creation myths take place before the world reached its present form in the most remote time – the first existing period of time known as the primordial age. The characters are normally non-human; they can be gods, demigods, and other supernatural figures. Myths are often associated with religion or spirituality and can be very important to those who believe in them. Some myths are used to explain how a particular reality came into existence, explaining why a society works and is structured the way it is.
