Most people who believe in God do so because they are brought up in households or even Countries that believe in god and they impress those beliefs on there children.

This certainly applies to organised religions like Christianity, Judaism or Islam anyway. For instance a huge percentage of the population of Israel is Jewish.

I on the other hand was brought up in a family with no belief in God what so ever. I was never told that i either should or should not believe in god and was allowed to make up my own mind.

Being of a technical and scientific persuasion, i like to have some sort of factual proof that something is true. Nobody has ever been able to show me anything that could amount to proof or even evidence that God is real therefore i do not believe in God.

I think part of the problem is this Belief thing. I do not believe in Ghosts, Monsters or Father Christmas either as to believe in them you have to suspend rational thought.
