In Norse mythology, the creation story involving the cosmic giant Ymir is foundational. Ymir is the primordial being from whom all life originates. According to the myth, the gods Odin, Vili, and Vé killed Ymir, and from his body, they created the world, including land, sea, and sky. His blood became the oceans, his bones formed mountains, and his skull turned into the sky. This narrative reflects the Norse understanding of the universe's cyclical nature and highlights the transformative power of death leading to new life.
