This is the reason I like steemit, since we can talk about anything like the existence of GOD.
I do not believe there is a so call GOD described in the religion books like bibble or ikran. I think that God was just created by the religion founder to control people mind and afraid of abandon his 'faith'，they just convince them there is someone watching them!
But what I believe there is creator built this world, who might not care what our world is happening at all, just like a coder who made a aromatic running game and not care it any more.
