as an agnostic (that would be someone who believes in a God, just not religion) i would have to say that your logic is flawed across the board. absence of evidence is not evidence.

the existence, or lack of existence, of a supreme, omniscient being who takes a personal interest in my daily life is a concept i have great difficulty getting my head around, it just doesn't make sense to me.

that being said, i have survived experiences in my life that should have killed me or earned me a private room with rubber wallpaper.
maybe it wasn't 'God' that saved me, maybe it was just dumb luck.

frankly, for me at least, it's moot. i believe we each choose to be 'God-like' or we slide into evil.
in other words, we can either choose to be good people, never hurting others willfully, never screwing anyone over (even someone who has screwed you over), never being dishonest, never giving in to the baser instincts we all have (we are all animals after all).
or we can choose to hurt anyone we please, we can screw everyone we come into contact with (especially those who have screwed us), and we can lie, cheat and steal any thing and any time we please and from anyone we choose. we can quickly come to believe that only our needs matter, screw everyone else!

for me that would be unacceptable, the reason not getting caught in a lie isn't as good as telling the truth is that you know the truth, you know you are a liar, even if no-one else ever knows, you will always know.

a religious man and an atheist were having a talk in Alaska some time ago and the atheist said 'I gave your 'God' a chance to prove himself and he failed.'
so the religious man said, 'In what way did you give God a chance?'
so the atheist responded, 'Well, i was lost in a blizzard a couple of weeks ago so i fell to my knees and shouted at the sky "God, if your out there, please save me!"
so the religious man said, 'Then you must believe in God because here you sit!'
so the atheist said, 'Nah, some eskimo came by and led me home.'

the point is, you shouldn't discount what you don't understand (and i don't understand it either)
