Well, i am a Atheist though i can see why those who believe in a god (or multiple lol) really believe.
It is in the nature of humans to find a cause for something.
People got to know everything, if they can't explain it they just make up something eventually or believe semi-logical things.
The theories of a god existing somewhere and that he shaped us all is very unlikely in my opinion, but hell, perhaps he is a very good hider and makes us believe things to hide himself or something.
I dunno.
