I am an atheist quite simply for the same reasons most people are theists. I’m not talking about the theists who think about these things or wonder how we got here.
I’m talking the majority of theists. Like them, I’m an atheists because I was raised as an atheist. I was never baptized, I was never forced to join or go to church and (unlike most here in Finland) never attended religious education in school.
Religion was a subject that was always treated neutrally in my family. Thor and Mars were always seen as equals to Moses or Jesus and both nothing more than myths and legends (tho I always thought Thor was much more badass than Jesus).
I can’t remember ever asking my mother why I attended ethics class while all the other kids on my age group had religion. I just kind of accepted it. In any case it wasn’t anything that picked me out from the other kids.
There are a few times I can recall thinking (with my then first or second grader mind) if there was a supernatural being watching over everyone and even a few times talking aloud to said being on the off chance someone was there, but it always seemed just a little too silly even back then.
Perhaps the question overwhelmed me back then, but in any case, I’ve never really believed in gods and I’ve never had, what some people call, “a religious experience”, I don’t even know that that means to be honest.
Today the reasons for my atheism haven’t changed. What has changed is my understanding of why other people are theists.
