Was raised Christian, but I started becoming aware of how hypocritical my church was around my middle school years. Did some reading, talked to lots of people. Refused to keep attending church by 8th grade.
Then, I didn't think about it for a while. Probably not until college. Started looking into other religions, but they all kind of had the same sort of overarching issues I had with Christianity. Even atheism, I found to be a religious-like belief.
I was really happy to discover agnosticism. I felt like it really spoke to me. I really don't like the idea that we're meaningless and nothing, even in the face of how small we are in comparison to the universe around us. I also don't like the idea that there's a magic all-consuming being out there who made us as we are who we someday have to answer to.
I like science and saying we truly don't know. I find comfort in the fact that we haven't learned our origins yet (as in, all of creation, not just humans). I like the optimism agnostics have, as it's a natural state for me to be in.
I like the way you put it. Also born and raised Christian. I considered myself an agnostic at 21 (now late 30s), but I'm an atheist for all intents and purposes. Atheist of the cool kind though, not like those anti-religion edgelords. I think religion has a place in society and works for some people, I respect that, it's just not for me anymore.
