This tunnel, built to ensure a water supply in case of siege, ran from the Spring of Gihon to the Pool of Siloam. This tunnel is recorded in scripture in 2 Chron. The second, also viewed by the author in 1985, is the garden tomb where Jesus was buried after the crucifixion. Scripture itself provided the information which led General Gordon to look for and find the garden and the tomb late last century. Although there are sometimes disputes about biblical sites these examples and others that could be quoted, I believe are undeniable evidence of the authenticity of the Bible.
World history includes many references to Biblical events.
For the new testament, Ken Chant tells us that during the reign of Emperor Tiberius there was a man named Jesus who was recognised by many jews as the Messiah and that he was put to death by Pontius Pilate. Also that Clement of Rome and Ignatius of Antioch were men who were personally acquainted with the apostles. In the Old Testament many of the prominent Hebrews were mentioned in association with the empires of Babylonia, Assyria and Persia, all of which are easy to verify in historical documents. All in all, there is sufficient evidence in terms of manuscripts, prophecy that has come true, archaeology and relationship to secular history, to be sure that the Bible is authentic. The faith of the Christian rests on what the Bible says.
