Belief is an integral part of the human psyche.... if you say that you believe in Nothing... you still have that belief in Nothing..... we are all frail mortal creatures who are absolutely ignorant of the consequences of death.... yes religion kills... if it was not religion it would just be something else.... science is a belief... our mathematical system is pure speculation.. for all we know somewhere in the universe two plus two could easily equal three... everything is pure extrapolation... theory...
