In extraordinary ways, modern archaeology has affirmed the historical core of the Old and New Testaments–corroborating key portions of the stories of Israel's patriarchs, the Exodus, the Davidic monarchy, and the life and times of Jesus.

The last time I saw "Mysteries of the Bible" on A&E, they found the happenings, but no proof the individuals were there or existed.
The walls of Jericho did come down but mno proof Josuha was there or even existed, he may have as I have not read up on it lately.
