Well, yes and no. Suppose that we found an SCP object, say, a sphere the size of a baseball that continually emits prodigious amounts of energy. We have no idea how it works, or where the energy comes from, and all of our attempts to find out just result in broken instruments. We have no idea where the object itself came from, either: It might, for all we know, have been manufactured by some civilization with technology far beyond our own, or it might be a natural phenomenon, and the universe just happens to contain these energy-balls scattered here and there. But we figure out that we can dump the thing in a really big tank of water and make a whole lot of steam that then drives some sort of enormous vehicle, that would be utterly impractical using any sort of energy source we do understand.
We understand the boiler. We understand the vehicle based on it. We made it. But we don’t understand the energy source that makes it possible. If it’s technology, then its maker presumably does understand it, but we don’t know if it’s technology. We don’t even know if it’s possible for anyone to understand it, so for all we know, it might be magic.
And people who disbelieve their own senses in favor of “science” don’t actually accept science at all.
