The Scriptures preserve ancient history for us. If we had to go with just the extent documents from the ancient near east, there are a lot of things we wouldn't know about. For example, apparently until recently there was a complete absence of mention of the city of Bethlehem before the Babylonian exile (outside the Bible).
Of course, we have always believed that Bethlehem was a real historical city, despite the absence of archaeological evidence, but now there appears to be some archaeological evidence in the form of a clay seal found in the "city of David" in Jerusalem.
But don't worry, atheists. The Bible's supernatural claims still have no predictive power, aside from things like the afterlife and the final judgment, which you can't experience yet. You'll get to experience them some day, but for now you'll have to be content with the predictive power of the Bible with respect to archaeology.
