For me i didn't become an agnostic , I just realized that I've always been an agnostic before... In fact i didn't even know that I'm agnostic, I didn't believe any superstitious as a child, i didn't believe in ghosts and other supernatural being.. I think i'm just lucky that i find science to be more interesting than joining religions.. I also got open minded friends they are very open in discussions even though some of them are indeed religious.. Evolution is introduced by my uncle since i was 8 year's old, in fact some of my relatives don't have any religion.. I guess that kind of thing kinda impacted my views on the world..
When it comes to me, thanks to my history teacher I started to doubt in God's existence. All those religious wars, Inquisition, the fact that clergy for centuries had a monopoly on education, made me think that religion is a man-made thing. A whip made by a privileged group of people to control the rest of the society. Religion is nothing else than politics, it's just a tool of propaganda. God is man's alter ego.
when I was 14, I had a science teacher who spent more time on the scientific method than on the actual discoveries of previous science. he would bring it up all the time, show how it related to shit like dating choices, learning to skateboard, everything, as well as showing how it developed the science that we do know when the lessons were about established facts and theories. He just hammered it in.
I started looking at everything through the lens of the method, and the logic behind it, and started seeing massive discrepancies in my religious beliefs and the bible, and the things I'd been told about my religion. I kept digging at it.
I immediately became skeptical of mainstream christianity, like within a couple of weeks of starting the journey. I started looking at fringe christian groups, the hippy groups, and that didn't pan out, so I started looking at other religions, at that point still trying to hold on to some kind of spirituality. Nada.
It took 4 years of exploring a lot of beliefs and systems, but by the time I was out of high school I was an Atheist.
I was a questioner starting at a young age, but had a devout belief in God/Jesus as a Catholic until I was 9 years-old. I was a logical-thinking child. I did not understand how just one group would go to heaven and other good people would go to hell. I could not understand the claims about God being all-knowing, hating evil and all powerful, but let child be abused from parents even if they prayed for it to stop. In college all the science that I learned supported my view that if there was a power higher than a human, it was humans as a group. It also did not help that I went to Catholic school, and saw "The Scary Dying Suffering Jesus" every day at church and before school. Really, a dying suffering dude, at a place for children, it is very odd when you think about it.
I also remember walking the long walk to school from church in long cold winters. The girls wore flouncy skirts with just tights and were not allowed to wear pants like the boys, after I while,Then, I also figured something was not quiet right with the whole church situation but could not name it. My lack of belief, as another person stated, became deeper as I was able to think abstractly as a child.
My path to atheism was very different. My family (including my extended, very large family) consisted of Irish Catholics. We went to mass regularly, said grace, etc. However I thought it was all wrong at a young age (probably at about 8-10). I have always been a very avid reader and read the bible (both old and new testaments). I also read many other things. I read everything with a very CRITICAL eye. Religion quickly made no sense to me. It was very obviously made up to control people.Science and the natural order of things did make sense however. So, I very deliberately became an atheist. I kept it to myself (mostly) but by my late teens I just put it all out there. Still do!
I was born and, after a few years, started to hear stories about a magic wizard who lived in the sky. I assumed right from the first time that these were just stories like Jack and the Beanstalk, Winnie the Pooh and all the other stories I heard. The dinosaurs I saw in books, though, were real - there were whole museums full of fossils to prove it. So in other words, I was born an atheist; it came as quite a surprise when I found out some people believed the sky wizard was real too.
One day in my late 40's I just woke up to realize that I didn't believe in the Christian dogma. It was shocking to me. I felt like the rug had literally been pulled out from under me and I was falling and. falling down the rabbit hole like Alice. I had been a believer I think, hook , line and sinker all my life. The accumulation of things along the way finally made it through my intelligence and blew the fog away. Free at last.
I’m pretty sure I always was. I had doubt very young in childhood and didn’t even know the words agnostic or atheist.. let alone their definitions. The whole religion thing made no sense from the start. The evolution from agnosticism to atheism took a bit longer.
I began to feel twangs of empathetic dissonance seeing good and decent people who happened to hold different beliefs from me as totally unworthy of going to hell ... a good God wouldn't judge so harshly, I thought. That may have been the beginning of my rethinking of the attributes of God. But it was the problem of evil that broke the spell entirely, and opened my eyes, for the first time, to a life without God.
I was raised in a very catholic household and then sent away to a horribly abusive catholic youth ranch for troubled teen girls. After three years on the ranch going through countless inhumane traumas and even being exorcised I officially turned my back on any idea of religion.
I had the usual childhood brainwashing of religion. I was told i must attend Sunday school for my soul to be saved by a gang of Christians that visited my estate. At secondary school in Religious education i spent more time growing eyes in the back of my head because of an unruly bully we had in the classroom who would punch other children in the face when the teacher wasn't looking than listening to the lesson. Where was God then?
Anyway fast forward another Ten years and i attend a fellowship called AA and that's when the force-feeding and the brainwashing of God really went into beast mode for me.
I was told that to stay sober i must pray every morning and every night to stay sober, plus attend as many meetings of AA as possible.
I did that for Eighteen months and i still drank again and to top it all i ended up in and out of homeless hostels in the UK for the following Twenty months after.
After going through all that not only did i realize there is no God but i saw that while i was praying to fictional entity i was not dealing with my problems properly.
The biggest frustration waking up one morning and realizing that you have wasted years putting your trust into lie who not even there to help you, when you could have spent the same amount of time doing a better job yourself.
I wasn’t raised particularly religious but did some time in Baptist, Lutheran and Catholic Churches and even a stint in Catholic school. I really tried to believe but I just never did. In fact, I’m convinced that most people, no matter how religious they pretend to be, deep down don’t truly believe. Instead, they fake it in order to fit in and reap the benefits of association with the other fakers.
I looked into comparative mythology, and realised the Christian story was just one more myth, with no more particular truth to it than any other. Perhaps it is a little more cleverly constructed around historical elements, but ultimately just another story.
briefly, i was raised as a secular jew, which means religion was not spoken of much in the family. we celebrated the holidays. we ate jewish food. my folks spoke some yiddish. god? not really part of life. he made a nice occasional invisible friend but that was that. i don't think i ever prayed in my life. age 14 i decided to check it out more and study judaism. after a year of that i realized that while i found talmud study interesting, i wasn't making friends or feeling close to anyone at shul. i stopped going. then i discovered that something my folks told me as fact, and which i had just accepted, wasn't true. they'd told me long-haired boys were dirty and rebellious and i found out that this was incorrect. i decided to question everything else i knew, too. some stuff withstood the test. god didn't. oh well!
Started asking questions at Sunday school that were not answered, was discouraged from asking those questions and told that I should not question gods plan and\or reasoning!
Thankfully even though my parents are Christians, they encouraged me to think for my self and never criticized my questioning everything!
I am 50 years old now. When I was around 7 or so I stopped believing in Santa Claws, and then within a few days after that I stopped believing in the easter bunny. I always had doubts about hayzeuz and god and the bible, but I am a very slow learner, so I did not fully recover from those beliefs till I was around 39. Strangely enough, my "fall from grace" started when I was around 12 years old and discovered masturbation. I had always heard how sinful that was, and that always sounded totally asinine to me. For any god to make something feel sooo fantastic, and be totally harmless to others, and make that be an evil sin that is punishable by the possibility of eternal damnation, would be just about the most evil thing any god could do, so that caused a wedge between me and christianity that slowly grew over the years. I started to believe more and more that even if that god is real, he is evil and deserves neither love now worship, and only hatred (if he were real). There was still that fear of hell if I did not believe, that was an obstacle for many years to give up on him completely, but when I finally got over that hump, I felt a great weight off my conscious, and my life was much happier after that, except for still being a miserable old cripple.
