I don't think that all UAPs/UFOs have a single kind of explanation.
That much seems obvious, doesn't it? Just look at the many "solved" UFO cases.
"Craft", "vehicles", "UAVs" or whatever, is still very much a viable option for some of the cases, such as the 'tic-tacs'.
Viable compared to what? How do you rate the chances of the 'tic tac' being a bird, say, against it being an extraterrestrial spacecraft?
That's probably my personal favored hypothesis at this point for those sightings.
Why? The evidence that UFO enthusiasts use to draw that conclusion is flimsy at best.
Like I've argued all along, I think that a terrestrial origin is most likely.
Your best guess is that the tic tac is a terrestrial "craft" or "vehicle" of some kind, then? That's the "most likely" explanation, according to you. What kind of craft or vehicle do you think it most likely is, then? And on what basis do you draw that conclusion?
I don't give very much weight to the 'temporal', 'supernatural' or 'extradimensional' hypotheses at this point, but I wouldn't rule them out entirely either.
How would
anybody go about ruling them out entirely? The only way would be to positively ID the thing as something other than supernatural, "temporal" or "extradimensional", surely.
What is "extradimensional", anyway? Can you give me an example of
anything that is "extradimensional" in the required sense? i.e. do we know of anything at all in our universe that has been confirmed to be "extradimensional? Or would UFOs be the first example of such a thing, if confirmed?
It's certainly possible that we are facing something new here, something unexpected that we've never encountered before. Something that might not have a comfortable place all prepared for it in our current ontology and worldview.
How likely to do you think that is, compared to UFOs having mundane explanations? On a scale of 1 to 10, say.
The "nothing to see here" option is just as unevidenced as the others.
I think it would be foolish to claim there's "nothing to see", and I don't think any skeptic is seriously arguing that. The arguments are all about whether there's anything especially extraordinary about what is seen.
Overactive imagination is probably the most likely explanation for many/most UFO sightings.
I think that most UFO sightings involve somebody seeing something (i.e. an actual thing existing in the world) that they can't immediately identify. Problematic leap #1 is the argument from ignorance, that goes: "
I can't identify this as something familiar, so it
can't be anything familiar". Problematic leap #2 is the step that takes one from leap #1 to "Because it can't be something familiar,
it must be something fantastical from my imagination (or the cultural imagination), like aliens or God or ghosts or time travellers." Neither leap #1 nor leap #2 has any valid justification.
