It is not necessary that we all agree to be Christians, atheists or communists. Our physical science has advanced, but our moral science has not. The reason we are on the verge of nuclear suicide is because our scientific advance gave us power, but our failure to advance in a religious moral sense did not give us the ability to control our actions for our own benefit. This exposes us to terrible dangers. We have the science and power of a modern nuclear age but the moral understanding of an ignorant savage of 2000 years ago.
Mankind is like a five year old child playing with a loaded gun.
If it is superstition, it is a threat to our survival, rather than an aid in securing it. Religion like science, is merely man's attempt to understand the world around him, and to manipulate phenomena in the environment for his own benefit. Obviously a religion or a science that was not true would not help him gain control over his surroundings. Anything that interfered with human understanding would reduce our ability to control the environment and ultimately reduce the probability of human survival. Superstition is not religion anymore than darkness is light.
