When I was young I was brought up without any conversation whatsoever on religion. I do remember returning home from school one day (Church of England, so we said the lords prayer at assembly) and I asked my mum, "Mum, is dad in heaven?" and she just looked at me and replied "Don't be silly, he's at work." That pretty much resolved my religious beliefs until I was around 14.
At 14 I slowly converted to Christianity and at about 15 I would probably have called myself an Anglican. This, however, went down hill extremely quickly. I remember my youth group got a talk from a parishioner who said we shouldn't listen to sinful music like 'Marilyn Manson' or other rock and roll. Me and a few friends went to our group leader after the guy left and said 'if you bring someone here preaching that bullshit again we're gone', I can't exactly remember how many weeks went past before I never went back.
After leaving, I quickly began realising that a lot of what I was being taught was complete BS, that they were trying to get me to question science. Well I'm a sci-fi writer, that shit doesn't stick with me. I quickly learnt that all the religious phenomena are merely a form of hypnosis.
Today I believe nothing. I am not an atheist, I see it as another bullshit religion just with a non-existent god at the top, because all I hear are people like Richard Dawkins preaching in the belief that there isn't a god... but any form of belief in the absence of evidence (the existence and thus non-existence of god is fundamentally unprovable) is FAITH, they have faith there isn't a god. I mean fundamentally Christians believe in the existence of a hypothetical entity, where as Atheists like Dawkins believe in the non-existence of a hypothetical entity. It's the opposite side of the same coin, where as what I believe most atheists really believe is that the 'coin' doesn't exist.
