Why Do You or Did You Believe?

[Dystopia]

For atheists who once believed I ask the same question:

Why did you believe?

And I add a second question:

What made you stop believing?

I believed because I was very young (less than 12 years old) and possess little critical thinking, it was simply the normal way of looking at the world. My parents didn't indoctrinate me even though they gave me the basis of Christianity (but I was never sent to have official religious educations with priests)

To answer your second question, I simply thought (about 13 or 14 years old) - "Why do I believe someone exists if I have never seen/felt/heard/smelled him? This simple question was enough and I guess I was always a functioning atheist, I just didn't stop believing earlier because my intellectual skills when I was 10 (the same applies to most regular kids) were not enough for me to think 'Does god really exist'.

I should note that after that I stopped being an atheist and became a deists of some sort by some time, but then again, critical thinking came back and atheism won the match inside my match. I guess I was always an atheist, I just never realized or accepted it at all times.
