Well hm. I guess here comes my little theory on how God exists in a different sense to me, or dosn't exist as it may be..
I belive that we are born with the thought of God somewhere in our brains, as sort of an instinct. I think it's natures way of morals and what not, yes you get taught them by parents and whatever, but theres a point where you become self aware of the morals even at an early age.. This 'instinct' helps us live our lives in a good way (most of us) and basicly, we arnt walking in God's garden, we are walking in his house, God is the world.. he IS the creation.. blah.. i'm rambling
Don't ask anyone to agree with me, just thats my opinion (although somewhat shortened down )
