Myths are used to celebrate cultural identity by encapsulating the beliefs, values, and traditions of a community. They often serve as a means of understanding one's heritage, fostering unity among people through shared stories and experiences. By passing down myths through generations, cultures maintain their unique identities, teaching important lessons about morality, existence, and social norms. Festivals and rituals rooted in these myths further reinforce cultural pride and continuity, enabling communities to connect with their history.
