Do we have evidence against the supernatural?

Only if he was saying that the IPU was natural because of things like air or a few parts of the set, would he be commiting composition, by applying that to the whole.But he's not, he simply saying that many natural things have the qualities of the IPU, so the IPU isn't necessarily inferred as supernatural.I think Ben's position is correct, in that there is neither evidence for or against supernature dependent upon which qualifies "evidence".Is the universe evidence of the supernatural? To the fundy next door it might be. But it has to be be decided as reasonable to suggest evidence should be there.Don't forget the argument from ignorance Lammy boy. If there is no evidence X did it then he didn't.
If there is no evidence X didn't do it he did.It's most easy to stumble upon these assumptions.
