I was kicked out of our local church when I was a child for asking too many questions... Well to be more accurate I got kicked out because I threw a tantrum after the way the vicar reacted to me asking too many questions, but I claim cause and effect on that one. There was just something about that attitude, that you're supposed to be interested in the religion, but you're not supposed to ask the wrong questions or come up with the wrong answers, or find anything disagreeable with it...
Anyway, I was just left to my own devices in figuring this stuff out and adopted nihilism as my belief system... or to be more accurate I adopted a belief system that was later explained to me to be essentially nihilism.
I don't hold that you can be certain any kind of divinity really exists. I know many people claim to have felt the presence of some kind of divinity, or spoken with one, or claim that these are the teachings of a divinity as was passed on by someone who had a spiritual experience, but I also know how easy it is to trick and fool the human mind into seeing or feeling things that just aren't there. So as far as I know, what's to say this isn't just a whole bunch of people making things up for themselves?
Of course by the edge of the sword I can't say for certain there isn't something there that people are in contact with. A lot of them certainly seem to feel so... So I don't claim to know either way, and I try to construct my morality and behaviour based on laws I build from the world around me.
