So, Sagasumono, if something can be described in words, it must exist? How about “The Great Sino-Aztec Atomic War of A.D. 107?”
I would also point out that I can easily imagine things which are verifiable and even repeatable but are not and would never be explicable. Let’s suppose that you’ve got Jesus Christ in a laboratory somewhere, and he’s in a mellow mood and willing to perform a few tricks on command. (Hey, he was willing to do it for the Apostle Thomas, why not for the 21st Century Scientific Community?)
So, we get a nice tank of distilled water, zero in a battery of scientific instruments on it (mass spectrometers and what-not), and then, presto, Jesus does his thing and you have a nice tank full of really good wine. Now, if Jesus is really just a space alien from an advanced supercivilization from another galaxy or something, we might expect to see something which would give us a clue as to what’s going on–a radiation signature, some sort of transition over time (“okay, at time t, it’s pure water; then at t+1, we see a trace of ethanol, and so forth until, at t+n, we’ve got a really good chardonnay with with fresh, spicy aromas and crisp, fruity flavors and just a hint of turpentine”). On the other hand, if he’s God, and is doing this because, fundamentally, the entire Universe exists by an act of his will in the first place, then you wouldn’t really expect to ever see anything like that. One minute, you’ve got water. The next minute, you’ve got wine. One femtosecond, it’s all water; the next femtosecond, poof, it’s wine. No unusual readings on the Geiger counter, no neutrinos, no thermal signature, no nothing. Just, “Hey, J.C., do that again!” “Okey-dokey.” “Well, I’ll be damned–uh, I mean, not literally, right, Big Guy?”
