Here is William Lane Craig’s take on the absurdity of life without God:
Man, writes Loren Eiseley, is the Cosmic Orphan. He is the only creature in the universe who asks, “Why?” Other animals have instincts to guide them, but man has leamed to ask questions. “Who am I?” man asks. “Why am I here? Where am I going?” Since the Enlightenment, when he threw off the shackles of religion, man has tried to answer these questions without reference to God. But the answers that came back were not exhilarating, but dark and terrible. “You are the accidental by-product of nature, a result of matter plus time plus chance. There is no reason for your existence. All you face is death.
Modern man thought that when he had gotten rid of God, he had freed himself from all that repressed and stifled him. Instead, he discovered that in killing God, he had also killed himself. For if there is no God, then man’s life becomes absurd.
If God does not exist, then both man and the universe are inevitably doomed to death. Man, like all biological organisms, must die. With no hope of immortality, man’s life leads only to the grave. His life is but a spark in the infinite blackness, a spark that appears, flickers, and dies forever. Therefore, everyone must come face to face with what theologian Paul Tillich has called “the threat of non-being.” For though I know now that I exist, that I am alive, I also know that someday I will no longer exist, that I will no longer be, that I will die. This thought is staggering and threatening: to think that the person I call “myself” will cease to exist, that I will be no more! …
And the universe, too, faces death. Scientists tell us that the universe is expanding, and everything in it is growing farther and farther apart. As it does so, it grows colder and colder, and its energy is used up. Eventually all the stars will burn out and all matter will collapse into dead stars and black holes. There will be no light at all; there will be no heat; there will be no life; only the corpses of dead stars and galaxies, ever expanding into the endless darkness and the cold recesses of space—a universe in ruins. So not only is the life of each individual person doomed; the entire human race is doomed. There is no escape. There is no hope.
If there is no God, then man and the universe are doomed. Like prisoners condemned to death, we await our unavoidable execution. There is no God, and there is no immortality. And what is the consequence of this? It means that life itself is absurd. It means that the life we have is without ultimate significance, value, or purpose.
