Myths shape collective cultural memories by providing shared narratives and symbols that bind communities. They serve as a form of historical record, preserving the values, beliefs, and experiences of a society. Through storytelling, myths convey important lessons and foster a sense of belonging among members of the culture, helping to form a common identity. As these stories are passed down through generations, they evolve while retaining core messages that resonate with contemporary audiences, ensuring that cultural memories remain alive and relevant.
