The myths tell them of their history, give them morals, teach them the Indian ways, and are part of their rituals. Without the use of myths the tribal people are lost.
Myths play a role in their everyday society.
Myths usually come from rituals. Rituals are performed and the tribal people pass the ceremony on by word of mouth which results in myths. In contrast rituals are nothing without the myths to follow. Many scientists will agree that myths are not substantial. Ritual needs mythology to be significant and teach the main point.
