BugEye, at the risk of seeming impertinent, I'll say: "Well, Duh!" Of course they're finding more evidence. The Bible is the history of the civilization of man.
I find it mysterious that the bible isn't used more as a practical text as opposed to a religious text. If you read the bible, ommitting some of the boring and not too important parts (Kings leaps readily to mind), it's a book that covers almost everything important in what it is to be human. Very little has changed, and we should realize that and embrace it for the value it has.
