Atheist ji,

It is a good question.

Why do I belive in the existance of a creator God?

*shrug* I really don't know I guess I just always have done so.

That by itself is probably not any good to you , but then if I was to ask you to consider the roots for some of your own belifes, I wonder what would happen.
