Mach, scientific theories have been disproven. See:
Obsolete Scientific Theories and Dr. Torch used to like to point out
Phlogiston Theory. So yes scientific theories have been disproven. But I think the point to take home from all of this is that this is part of how science works, it is a self correcting process. When a hypothesis or theory is shown to be incorrect, science throws it away and moves on to that which explains better.
Back to my original point, Huckabee says he would take God's word over science because God doesn't change. Well from a scientific point of view that's a bad thing. If scientists still subscribed to Galileo's view of how the solar system worked, satellites would be crashing into planets instead olanding on them, or better yet zipping off into space never to be heard from again because the calculations do not work as well as Kepler's. And that goes the same for Newtonian theory of gravity vs. Relativity. Some day, the theory of relativity may also be supplanted by something with even more explanatory power. If Kepler, or Newton, or Einstein had said, "These calculations cannot be correct, because the Bible says different." we may have never tried to send spacecraft up for fear of hitting the firmament unless the windows were open.
That is why I can't vote for Huckabee. He is saying no matter the evidence, he will base his decisions on the feeling in his gut and what he thinks that God is telling him. That's bad thinking, and if we're going to send more soldiers off to war, I don't want him ignoring the evidence to fit his perception.
