Apparently the scientists with their preconceived notions of what qualifies to be observed and what doesn't.
They're working on the assumption that the supernatural can't be found out through the scientific method, and arbitrarily assign the label to something that they don't even know if it IS supernatural.
You raise an interesting point, though. The GToE is not required for the scientific advances that we've enjoyed anymore than beer is required to be sold at highschool football games. The GToE has held back further enlightenment for over a century. Eventually it will be discarded, esp. as new evidence (such more living fossils, esp. something big like a nocturnal pterosaur alive and well in 2014) comes to light... Some of us are working on this diligently...
