To me, this is one of the most puzzling aspects of so many paranormal claims. Once you invoke a phenomenon like this, how can you claim to know anything about it? When someone claims to have a video or photograph that "must" be a ghost, for example, because (they claim) it's otherwise unexplainable, I want to ask: what are the characteristics of a ghost that allow you to identifiy it as such? How do you know it's a ghost, and not an angel, a demon, or an alien? What properties does a ghost have that distinguishes it from any of those other paranormal entities?
As you suggest, the same applies here. Once someone claims that bigfoot is coming via wormhole from another galaxy, he might just as well be saying literally anything. What led him to that specific conclusion, I wonder?
