"Unlike animals, humans know they must die. This awareness forces them to think about the beyond, which remains so regardless of whether it is inhabited by God or nothingness. This makes the future unknown to humans and the hidden trace of their secret anguish. We are not anguished by “this” or “that”, but by the nothingness that precedes us and awaits us. And since there is nothingness at the beginning and end of our lives, the question of the meaning of our existence arises unavoidably. An existence for nothing or for God?"
