The mythical beings known for their powers of creation and destruction include deities from various traditions, such as Gaia in Greek mythology, who represents the earth and fertility, and Kali from Hinduism, symbolizing time, change, and destruction. In Egyptian mythology, gods like Atum initiated creation, while others like Seth were associated with chaos and disorder. In Norse mythology, Baldur's creation as the beloved god contrasts with Fenrir, the wolf fated to bring destruction. Together, these figures emphasize the duality of life and death in understanding existence.
