Also, in the absence of a present and readily perceivable god, that's all we ever will have. The discussion of "proof" simply cannot advance in a meaningful way while god remains hidden. We already have the Bible, and it is a finished product, unable to be added to, because there is no more Jesus, no more burning bush, no more overt acts by God to influence mankind, and we know this because the Bible tells us that Jesus is the final covenant, and there will be no more.
It is an exceedingly convenient situation for the Church, because they can continue to point to the Bible and demand that it be accepted wholly on faith, without any proof. It's just that the world is, more and more, unwilling to rely on such explanations.
