Hi Jovaro (will try and find you tomorrow if you are online)
What proves the Bible? History does. The Bible itself is supported by plenty of historical evidence which supports it's claims. The evidence both supports the biblical text itself and also the historical claims of the text and the ways the Bible came to be in the form it is today.
Others are asking similar questions in other forums, so give me a day or two and if no one else answers in the meantime, I'll post some of this historical evidence for you. Bible and Church history is actually quite interesting reading.
Just found this website which I haven't really checked out but on a quick check it looks very good reading. try and it and see what you think.
