Beep. Circle takes the square. Science says, by definition, the supernatural is untestable (if it was testable, it would be natural). It does not say the supernatural is impossible -- in general it has very little to say in regard to the supernatural.
It has a lot to say ABOUT those who choose to believe in the supernatural. If one chooses to explore intelligent design, even if from a scientific background, that person is then written off. You need only look at some of the posts around FR to see that no respect is paid to those who choose to explore this theory, by those in the scientific community. There is only hostility.
