Experts have done the calculations on the probabilities and those results showed that the probability that real objects, which in many cases looked and behaved like craft, but were of "unknown" origin, and therefore synonymous with alien, but not necessarily extraterrestrial, is a virtual certainty.
The persistent and dishonest attempt to redefine terms to make "UFOs = alien craft" is noted. Here is a constructive contribution which "ufologists" would do well to heed: Dishonesty of that sort is tantamount to lying, and although clearly acceptable within the pseudoscience of "ufology", it is generally not an acceptable method of relating to other humans in this society, in the real world, on
this side of the reality/fantasy border. Here's another constructive contribution: No "ufologist" has yet once advanced the discussion one iota with their attempts to dishonestly redefine terms.
Is this the same as proof? No. Is this the same as material scientific evidence? No. Is it a good enough reason to take the topic seriously? For most rational people it should be. But not everyone who thinks they are rational are. Some people, including some people who did the study didn't form their opinions based on their own results, deferring instead to their some bias or perhaps kowtowing to the decree of the establishment that wanted flying saucers downplayed. Some people go so far as to ignore the study altogether or simply dismiss it as irrelevant because it defies their paradigm.
Speaking of paradigm, in this study to which you refer, or in any other study ever undertaken by man, in all of that human experience that you wish to use as a reference, which of them concluded that any particular sighting was indeed an alien craft or for that matter, that alien craft exist?
Oh, and here is another constructive contribution: Appealing to paranoia of the establishment and fantasized conspiracies to downplay alleged knowledge of alien craft only adds a layer of desperation on top of an already ridiculous -- and failed -- attempt to make "UFOs = alien craft".
As for those objects in UFO reports that later turn out upon investigation to be something natural or manmade, so what? Simply because most objects in UFO reports do not turn out to be alien craft doesn't mean all the objects reported are not UFOs ( alien craft ).
Thanks for demonstrating once again that you're not willing to answer a direct question, as easy as the answer is. The question wasn't of all the things apparently seen and initially unidentified as some particular thing, how many turned out to be natural or man made objects? That was not the question, your dishonest attempt to reconstruct the question in order to avoid honestly answering the actual question notwithstanding. The question that seems to strike fear into the hearts of "ufologists" is this: Of all the things apparently seen, and at first not identified but eventually identified as a particular thing, how many of those turned out to be alien craft?
That is the question that apparently no "ufologist" has the courage or honesty to answer.
I've talked with many people over the years and most of their stories could be explained by something natural or manmade. But a very few could not ... or at least it didn't seem likely based on the probability of spontaneous simultaneous hallucinations, or hoaxes or other non-material explanations.
Yeah, well, your arguments from incredulity and ignorance haven't gained you any ground yet. You certainly can't rationally believe trying another round of them will help. Interesting that only the skeptics here are providing constructive contributions. The "ufologists" are repeating the same old useless anecdotes and trying the same old failed strategy of hoping a lie or logical fallacy might slip past the watchful eye of the ever vigilant skeptics.
So basically I've been doing what you suggest all along, that being that I always bear in mind that there are a lot of other possibilities to explain the objects in UFO reports besides that of alien craft, and I do what I can to elimante as many of those possibilities before arriving at an opinion regarding the probabilities one way or the other.
That is, of course, another dishonest attempt to re-frame your position to make it appear skeptical. Shall I post the links... again... to all the quotes where you've tried to dishonestly equate "UFOs" and "alien craft"?
Personally, I am fairly strict so far as ufologists go.
So you're strict as far as pseudoscience goes? Pardon me while I have a good chuckle...

Okay, back.
Because I don't have all the tools or authority at my disposal to do an in-depth study of each case, [...]
We haven't really seen any "ufologist" do an in depth study of any case. The only ones ever to make a constructive contribution to this thread are the skeptics. "Ufologists" start with a foregone conclusion that some UFOs are alien craft, then they apply whatever strategies they think might work to convince themselves that they are correct. (Notice how well those strategies of arguments from incredulity and ignorance, dishonestly redefining terms, avoiding questions, avoiding research, avoiding critical thinking, and building straw men have worked to convince anyone who wasn't already a believer in the faith-based position that "UFOs = alien craft"?)
[...] unless the person I'm talking to describes something that leaves very little doubt, I reserve an opinion based on insufficient information. For example an odd looking light in the distance that isn't identified, but is normal in every other way is not sufficient for me to class it as a UFO. If on the other hand it goes from a dead stop to streak across the sky in a second or two, I'd pay more attention, and if it also instantly changed direction as well. I'd pay even more attention, and if upon further investigation there were other independent witnesses who say they saw the same thing at the same time from another location, then I'd take it seriously enough to say there was a high probability that the object was some sort of alien craft.
Yet after having been asked literally dozens of times, you refuse to elaborate on how you know everything about every conceivable thing that might cause someone to perceive such a thing or to say they've seen it if in fact they didn't. You have yet to answer the simple question of how you've gone about eliminating the possibility of the other infinite number of things that are not known to exist, and irrationally and un-skeptically landed on that singular conclusion that it must be an alien craft. Didn't you learn anything in the thread where everyone tried so hard to help you understand critical thinking, what it is and how to apply it, and how your neglecting it is the root of your failure?
But even then would I declare with absolute certainty that it was? No.
I think we can safely, and without any beating around the bush, place that comment directly into the "lie" bin.
I've only done that with my own sighting, and that's only because of the various facets of the observations I made ... and of course I'm sure you would add, my belief that those observations were accurate enough to reach my conclusion at the time and have remained uncorrupted enough to believe the same thing today.
Constructive contribution: You overestimate your ability to effectively remember details. You have provided much evidence to support the notion that your very own fairy tale UFO sighting is a work of pure (and not very imaginative) fiction, a hoax. You have no basis of reference in all of human experience to suggest that anything you claim to have seen could possibly be something which is not known to exist.
And in case you've forgotten: Of everything that has been apparently seen and initially unidentified, but which was later identified as some particular thing, how many of those things turned out to be alien craft? Come on, looking for an honest answer to a simple question here. Can you do it? Can
any self proclaimed "ufologist" do it?
