It has always been pretty obvious to me that if you truly don't beleive in God then you will never find him and hence for you he will never exist.
If I were to ask you if the orange I am eating is sweet or sour what would be your reply? You wouldn't know, of course, you are not experiencing what I am when I am tasting the orange.
He exists for me, I believe in him and have felt his influence in my life. Am I better than you for that? I guess that would depend from which perspective you wanted to view that from. It wouldn't be for me to say.
