Life arises out of death.

“Life rises out of death, death rises out of life; in being opposite they yearn to each other, they give birth to each other and are forever reborn. And with them, all is reborn, the flower of the apple tree, the light of the stars. In life is death. In death is rebirth. What then is life without death? Life unchanging, everlasting, eternal. What is it but death - death without rebirth?” 

Ursula Le Guin
