Humans have used myths to describe or explain things that they couldn't have comprehended otherwise. Myths served as the basis for rituals by which the ways of humanity and those of nature could be psychologically reconciled.
Myths are an important part of every society, including our own.
Without at least a basic understanding of a cultures myths it's impossible to fully understand that culture because myths express a societies beliefs and justify it's institutions, customs and values. There was once a Heavenly Prince who asked his father, the Heavenly King, to give him the beautiful peninsula of Korea to govern. The King granted his wish and he went down to Korea with three Heavenly seals and 3000 followers. He landed in Korea under a now sacred sandalwood tree. Here he established a sacred city with three ministers to carry out his orders.
