greenman, here is a good example for you. science knows without doubt that dark matter exists, but they have not so far to my knowledge been able to see it. as a matter of fact a scientist once said that perhaps when they see and learn the secrets of dark matter, maybe then they will come to know who and what god is. i believe that one came from paul davies who IS a scientist. people believe for many reasons and people disbelieve for many reasons. i guess the better question would be for you to explain why you don't believe so then we would be able to address this question in a way in which you could understand where we are comming from. for myself, i believe there is a god simply because too many strange things have happened in my life for me to ignore the existance of god.
