I was raised in a church of god. Soon after high school I started really looking at the bible rather than just believing what the preacher was telling me. I realized in was all just a crock of shit.

I did at an early age. I went to Catholic grammar school, and found myself questioning faith around 4th or 5th grade. I considered myself an atheist in the 6th grade, yet didn't make that public until I reached high school.

Because the private (Catholic) schools had a far better education than the public schools I could attend at the time, I ended up going to an all-male Catholic high school. This is where I started to get in trouble because of my lack of faith. I clashed with teachers that taught Religion (shocker, only Catholicism) and Morality (shocking, another bullshit Catholic class) to which I was awarded with trips to the Dean, and multiple detentions.

After high school, I no longer had any ties with forced religion. I'm lucky to have a mother, though a practicing Catholic, respects my beliefs. We don't debate religion, but do talk about it from time to time in regards to current world events.

i was 16 and one day i was a christian who completely believed in god and the next day i wasnt. i can't remember when the change happened

I already thought most religions were stupid growing up and I only went to church for the snacks. Eventually i started watching a lot of youtube and seeing all the religion debates about 7 years ago and the atheist switch was flipped.

I was about 15 when I met my first atheist who also happened to be my boyfriend. I realized about a year later that I found the idea of any supreme being being in control to be absurd. I had gone to church regularly from a young age and it never had any effect on me. I usually slept through the service or doodled on the tithe envelopes. I did become angry when I heard a preacher denounce gay people and one day in Sunday school my little brother came out crying because of something the teacher had said to him. That was the last time I went to church. I was 12.

I started leaving my religious roots in my later high school years, but it wasn't until my early college years when I learned about Atheism and famous Atheists like Hitchens and Dawkins, and found Atheist groups to attend.

Probably in my late 20s and I'm in early 60s now -- although I've never fully believed, even as a child. I went to different churches with friends and as time went by, I stumbled upon Eastern religion which made so much more sense. I haven't studied it extensively but its more about looking INward rather than praying to some "Santa Claus in the sky".

I was never raised in any religion by my parents my Mom grew up Catholic but my Dad hated religion.
Over the years I never gave it much thought either way, I simply didn't care until a few years ago.
Then I started to get interested in politics and I started to become very angered by the far right, evangelical GOP politicians who were trying (and in many cases succeeding) in getting their religious beliefs passed into laws.
This all made me look at the concept of a god and the more I thought about it the more ridiculous it was.
Now at this point in my life, god is no more real than the tooth fairy.

When I was 5 my parents made me say Jesus could live in my heart and I didnt want someone to live in my heart. I was scared put off and I think I cried. At 12 I was a skeptic and remember questioning "proof" of religion vs science. College - full atheist maybe sooner. 21 realized all the implications. : )

I was about 22 years old and I'm now nearly 71. It was a gradual process and I was in the closet except for maybe two people until just two years ago when I retired.

10 months ago when I came to terms that all the miracles described by main stream religions where a mixture on coincidence, scientific phenomenon and myths.

I was about 7, in Sunday School. They told me Jesus wants to save me. They asked me if I could hear him knocking at the door of my heart. I cried and said yes and they were moved and gave me kool-aid in a paper cup and a cookie. But I cried because I felt nothing and I said yes because I was ashamed and afraid. Over the years the more I doubted the less I feared damnation. It wasn't till my teens I realized I could find my own purpose in life. And I was in my 20s when I realized the oblivion of death was not infinite darkness but the same oblivion I was born from and would someday return to. "I do not fear death. I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it." - Mark Twain
