I just came across this and I showed it to a few Christians that I know and they had no response at all.

Obviously they had no training in apologetics and Christian evidences.
This is the long version, in fact it is an e-book which I challenge you to look through.
Shorter version
Any book can make what ever claim it likes, but can thos claims be substantiated. While not being a text book the Bible makes various statements about the world, which were not discovered by modern science since fairly recently. (A sample of them are in that link)
How could the writers know, without divine inspiration?
Now one thing you have to know about the Bible is that it is actually a collection of sixty six books, written in more than one language, by several people from all walks of life over several centuries.
Yet it all fits together.
The Old Testament came together by the first century CE, and the New Testament with in a very short time compared to other historical documents.
If you look at various prophecies with in the various books, you find an amazing amount of prophecy fulfilment. One author names a specific person, several years before he ascends a throne.
And as for the Messianic prophecies, try fulfilling all of them, even to deciding where to be born.
We believe the Bible to be the word of God, not only because it tells us, but also because the things it says about the world not known until recently and the fulfilled prophecy contained with in. This points to it's divne inspiration which substantiates the claim.
All done without circular reasoning.
