So, if you had access to it, do you think you could actually prove, beyond all possible doubt, that my desk was *not* a shape-shifting alien that just happened to be perfectly mimicking a desk? If not, does that mean you'd believe me if I claimed that my desk *was* a shape-shifting alien?
Realists, feel free to state any ways you can think of that the suggested proofs, or any you come up with, could be explained away by the shifting, intangible, and/or unknown properties of shape-shifting aliens.
