Christians lol are taught by their god. Yes there are pastors and folk that talk about him, but he really is the one that reveals himself. So you can I suppose lay the blame of believing in god solely on those who talk about him, and yet, he never becomes really real to anybody that has only heard about him, atheists have heard about him, he becomes real to those he teaches himself. So now we have christians believing in this invisible non-existant god, and to top it all off, they are taught by him, and to make matters worse, he does not exist.
So...what is it about the human mind of a christian, that not only believes in this god, but actually is taught by him. He is not only a figment of our imagination, but he is also the one that changes our behaviour. So then if this non-existant god only exists in our minds, fair enough, but for this non-existant god to change our behaviour....what is that? How does a figment of one's imagination change your behaviour? That sounds like we are crazy...and then well....there must be some scientifice method to prove that.
