I'll say it again: "If science only tests the natural world they don't test the supernatural world and therefore have no merit to evaluate it."
To be honest, I understood you the first time. In fact, I agree. Let me help ...
Strahler ventures onto the turf of philosophical naturalism when he points out how supernaturalism’s lack of methodology renders it metaphysically sterile, in effect pointing out the inseparable connection between epistemology and metaphysics:
In contrasting the Western religions with science, the most important criterion of distinction is that the supernatural or spiritual realm is unknowable in response to human attempts to gain knowledge of it in the same manner that humans gain knowledge of the natural realm (by experience)…. Given this fiat by the theistic believers, science simply ignores the supernatural as being outside the scope of scientific inquiry. Scientists in effect are saying: “You religious believers set up your postulates as truths, and we take you at your word. By definition, you render your beliefs unassailable and unavailable.” [Arthur N. Strahler, Understanding Science: An Introduction to Concepts and Issues (Buffalo: Prometheus Books, 1992)]
This attitude is not one of surrender, but simply an expression of the logical impossibility of proving the existence of something about which nothing can possibly be known through scientific investigation. [

The difference between Strahler's comments and your dismissive quip is that one clarifies while the other obfuscates.
By the way, Forrest's discussion regarding methodological and philosophical naturalism is really quite good. You would do well to study it.
