In Norse mythology, the event that leads to the rise of new life after Ragnarök involves the rebirth of the world through the survival of gods like Vidar and the emergence of a new generation. After the cataclysmic battle destroys much of existence, the earth rises anew, fertile and rejuvenated. This cycle of destruction and renewal emphasizes the themes of life’s continuity despite chaos, illustrating how myths convey hope and the promise of rebirth amidst despair.
