Trying to learn and make sense of Christianity drove me towards atheism.
I grew up in a really religious town. I went to an Episcopalian school from 1st to 9th grade and we had service every morning before school. I went there because the education in my city was crap and this place was the best in town.
My parents were agnostic or maybe slightly Christian, but I never heard a bit about religion from them growing up. We did not go to church.
Despite going to church service at school every morning, the whole concept of Christianity did not make logical sense to me. So, around 4th grade I begged my parents to take me to church "like everybody else". My 10 year old logic told me that if everybody else was doing it, it must be the right answer.
I took classes at this church so I could be baptized. In these classes, I tried to learn as much as I could, but things still didn't make sense. The more questions I asked, the more things didn't make sense. The more I read the Bible, the less the Bible made sense.
I ended up going to three churches (Methodist, Presbyterian, and Baptist) between 4th and 5th grade. I went to classes twice a week. The end result was that I realized Christianity was bullshit and I became atheist shortly thereafter.
