Thoughts of the Century?

This blog is going to answer something based off a friend, what I have been thinking, and what I have been learning the last few months. The first question is Can Christians prove that 1. God does exist? 1A. If so can we prove it with out using the Bible? 2. If we can not prove it with out using the bible are we believing the truth? How can a book (yes I know it's God's book) but to an unbeliever in faith its just a book make something exist? But before discussions can look at this or any other "important" data we have to wonder how will we agree on anything? How do we know anything at all? Can we know from experience, from tradition, from data, from intution? If you answered yes to any of theese, please let me know. If you answered no to any of these let me know that too. I do have a point but you will have to work for it.
