Myths engage with the concept of heritage and lineage by reflecting cultural identities and values through the stories of ancestors and gods. They often explore themes of belonging, duty, and the legacy passed down through generations. These narratives can reinforce societal norms, shaping how communities perceive their roots and influence their collective future. By emphasizing the importance of lineage, myths encourage individuals to reflect on their personal identities within larger cultural contexts, fostering a sense of continuity and connection with the past.
