i'm not really sure where to go with this response
just as belief in God or any religion (i'm talking genuine, intelligent faith here, not brainless zombie faith) is something that you have to work out yourself, so is non-belief. there's little that we can say to make you not believe, we can present to you ideas that you'd have to sort out on your own.
if thats what you're looking for, i can try and help you out, if i can.
