>>Very cute. The current definition excludes all alternatives other than naturalism. <<
OK, tell me how you can use, measure, define and apply supernatural phenomena.
What's supernatural got to do with it?
If I find a watch on the beach, I don't assume it was created by a supernatural being. Neither do I assume it evolved.
If the sudden appearance in the Cambrian is better explained by a designer, that says nothing about who or what the designer is. "Supernatural" is a red herring thrown out by evolutionists so they don't have to answer which fits the fossil record better.
If God happens to be one option that fits the bill for the designer, so be it.
Besides, only God is natural. Everything else is a creation.
