 You can see an altar of uncut stone at the foot of the mountain where there's evidence of burnt sacrifices right where it should be. There's evidence of bull worship, and you can see exactly how Moses would have seen the golden calf worship going on as he came down from the mountain. There's a brook that comes down from the mountain just like the Exodus story says. You can see right where the cave of Elijah might have been. All of these little details have to fit, and they fit.
