I realize I may have misinterpreted your response as hostile when, in fact, I shouldn't have.you've never from your early childhood believed in a higher power than yourself?
In answer to your question, I was raised in a religious household. As my critical thinking skills developed and I began questioning what I was taught, I came to realize how improbable that it was actually true.
I'm the type of person that likes to know whether what I believe in is true or not. Faith (belief without evidence), doesn't cut it for me.
Hope this answers your question in a more thoughtful manner.
