Whenever people try to engage me in a conversation about God, or religion, I merely stated that I could believe in Santa Claus a long time ago.
Everyone believes in evidence and reason. That is what gave us our technology.
Oddly enough, when it comes to religion, many people brush this rational, evidence based, thinking aside in favor of faith (faith being believing in something regardless of evidence).
Faith is what children use to believe in Santa. Should adults use this same method to believe in a god?
