Yes, insulate your beliefs at any cost.
I know that most adhere to that notion - to include most scientists. I do not share that position. While it is true that all attempts to test the supernatural via experiment have failed ('explained' via special pleading (God cannot be tested! Maybe God just didn't want to answer that prayer! All part of 'the plan'!) for the most part).
My position is that at least some of the claims of supernatural action should - even must - have left physical evidence or other corroboration. And when such evidence is not present, it should count as evidence against the supposed supernatural event.
Global flood, for example.
Like the ICR?
But they don't bother to do that kind of thing. No creationists do. They just try to nitpick real science, and they nearly always fail. Or they
lie, and
get caught doing so.
