That sounds like circular reasoning to me - you seem to be saying that if we can observe something it must therefore be entirely natural.
That doesn't follow, though. The obvious example would be that if Jesus actually rose from the dead by a miracle, then people who were present could see him and put their hands on his scars.
Is the supernatural inherently not scientifically testable?
Absolutely.
It does not follow that it could never be observed at all, if it exists.
