I was accidentally raised atheist by my parents. They took me to church, but never, ever talked about god to me or told me what to believe. At the same time I was taught only to believe in something that has evidence and to understand science trumps the bible every time. Atheism was my inevitable destination.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
