I had a rudimentary belief in the xian god up until around 12 years old. I was brought up catholic. My belief really just consisted of a general fear that I was being watched. I recall finding a porno when I was about 10 and suddenly wondering if I would go to hell for looking at this topless woman.
Around 11 or 12, I started asking questions. My final question (and sunday school/ccd lesson) was when I approached a priest and asked him why god was hiding. The priest was furious, and in front of everyone told me that I was evil for questioning god. “You just don’t question those things.”
That was it. He had revealed how it worked, and I could see that it only worked when you suspended disbelief, didn’t question, and abandoned logic (which I was just fine tuning at that point).
That was 27 years ago. Still an atheist.
