Prove?

Christians say that the bible gives us prove that god is real. I believe in god and all the bible has to offer.  But if the bible gives us prove, than muslims have prove from the quran. And mormon have prove from the book of mormon. So do we really have prove that the bible is real? We know that god is real because we have relationships with him but no prove. So don't tell people that the bible is are prove, 'cause its not, are relationship is. So think about that and please tell me what you think in the commet box.
