If this is David's Palace, that's great, but in no way does it "prove the Bible" to be true. After all, Jerusalem exists - but just because the Bible talks about it doesn't make the Bible true.
Why do you people keep reading that I am citing these things as making the bible true? I'm not, and it doesn't. What it is though, is evidence that supports the bible's historical accuracy.
And yes, arach is right, this should be in bible accuracy and innerancy. I neglected to put that in the OP because it is a spin off topic from the pool.
'Now isn't it amazing. I tell you that nobody made a simple toy like that (solar system model) and you don't believe me. Yet you gaze out into the solar System - the intricate marvelous machine that is around you - and you dare say to me that no one made that. I don't believe it'. -Sir Isaac Newton
