If the aliens were smart, they’d disguise their saucers as pink flying cows. No report would ever be taken seriously. Clearly, we only get visited by the dumber kinds of extraterrestrial. ---

Most UFOs don’t have running lights. That’s why we don’t notice them hovering over New York, London, Paris, your bedroom window . . . ---

How would we expect extraterrestrial spacecraft to appear? I would say, given the advanced tech, that if they’d chosen visible craft, I’d expect a few WTF features from our perspective. And I’d also like to try to reclaim the term UFO. I once saw a UFO. I don’t think it was of extraterrestrial origin. ---

> [@Kobal2](#): > > That’s a faulty syllogism. Cats have paws. Many dogs have paws. Simplest conclusion would be that dogs are cats. I cant tell if you are playing devil’s advocate or what, but this analogy is bullshit. It would be apt if you said “bigfoots are furry…I saw something furry. I saw Bigfoot.” Dogs and cats are tangible and substantiated, so speculating a furry, pawed creature being one of these things we know _do_ exist would be reasonable, if still incorrect. Manifesting a fictional new creature=alien theorists. That mentality is how bumps in the night become ghosts and so on. And of course not _every_ misidentified object in the sky has to be something manmade, which is why no one has said that. Things with blinking lights, esp ones that make shape formations really tend to indicate terrestrial aircraft. But if you have a single reasonable explanation where the most logical, simplest and reasonable conclusion of the sky-thing being aliens, argue for It. That is what the op was asking…for a reasonable excuse as to why defaulting to aliens would be the most logical answer. So…? Why’s is aliens a better answer, logically? ---

> [@Dr.Colossus](#): > > I cant tell if you are playing devil’s advocate or what, but this analogy is bullshit. I am indeed playing devil’s advocate to some extent, but it’s not an analogy at all - it’s an equivalent syllogism, in formal logic terms. Faulty syllogisms are bad and you should feel bad ! 🙂 Occam’s Razor and syllogisms have their place, and they are valid logic tools when used properly - but you’re employing them badly in this case, that’s all. Doesn’t matter that the conclusions you draw from them are correct (for a given value of correct - as I said, there are plenty of equally and more often than not more adequate explanations for given UFO sightings than “aircraft”), the path you take to reach that conclusion is still wrong ; and my high school math teachers would award you no points for a correct result reached by incorrect means. The utter\*, \*utter _bastards_. No you betweeded fucks, I haven’t forgotten, and I haven’t forgiven. **Soon**. > [@](#): > > And of course not _every_ misidentified object in the sky has to be something manmade, which is why no one has said that. Things with blinking lights, esp ones that make shape formations really tend to indicate terrestrial aircraft. That’s really the thing - they don’t necessarily, not by a long shot. Do read up on autokinesis. Fast moving blinking lights in the sky, zipping around at extreme speeds, making improbable turns or positioning themselves in “geometric patterns” and “formations” are exactly the sort of things one can perceive watching lone, immobile stars or distant ground light sources at night in the “desert”, especially when under stress, intoxication or sleep deprivation. It’s really quite fascinating and dare I say wondrous a phenomenon. Atmospheric & cloud patterns also “work” just as well - I’m just more personally partial to biological wonky as a concept and source of wonder. But I’ll readily admit, I’m easily impressed and get a perverse kick out of human imperfection 😛 > [@](#): > > But if you have a single reasonable explanation where the most logical, simplest and reasonable conclusion of the sky-thing being aliens, argue for It. That is what the op was asking…for a reasonable excuse as to why defaulting to aliens would be the most logical answer. I don’t - for one thing I don’t believe in alien visitations, for another I don’t believe there is a single explanation for all UFOs, or even each discrete subset of UFO sightings. Reality is messy and complex as shit even before you introduce human factors. Nor do I suggest defaulting to aliens as the most logical answer - I’ve just given you a laundry list of phenomenons any given sighting could be (and should be ruled out) before one goes to little green men… or to military planes. And in my profound ignorance, I’m probably forgetting/ignoring about a hundred others. I’m just saying that you’re just as utterly wrong as crack UFOlogists are when you handwave the problem away as or reduce it to “it’s human made, duh” based on nothing but facile and faulty logic. Even when and if it really is human made. ---

(anecdote: i saw it on the side of the road on the truck coming out of st louis and said “people are going to say that’s a ufo, just you wait…”) drawing a conclusion based on a variety of convincing evidence isn’t “faulty” logic. it is if you build a strawman and pretend i have some dogmatic belief that every UFO is an airplane–but i can’t help you making that up. i never said it. and dismissing a decision based on logical evidence as “faulty” is exactly the mentality paranormalists cling to. they say “hey, now–HOW CAN YOU BE SUUUURE?! you have to consider every possible thing, even the most ludicrous and insane.” that is what they need to make their belief structure work–but it’s bullshit, they don’t live their day to day life that way–and neither do you. you (and them, which i am calling “you guys” from now on) don’t agonize over bent light and flaws in perceptions when you go through green lights. you have faith built on evidence and just trust that there’s not some dimensional curvature in time-space that makes oncoming cars invisible. you don’t wait to consider every possible scenario before pressing the gas (hey man, you could have had an aneurism that makes you think the light was green when it was red. you could have just had a stroke, etc etc.) the point is it is impossible to live life that way, and none of you do it. call it a faulty syllogism, but the rest of mankind (and you, when you’re not being contrary) make well informed decisions based on evidence. that’s not faulty. it’s just how life works. so… go back and re-read the OP. i asked something about blinking lighted aircraft that people call UFOs. i asked about THAT, SPECIFICALLY, and now you want to argue about swamp gas and unlighted shiny things and balloons and birds and i don’t even know what-all, as if i was referring to every known ufo sighting ever in history of all time. i wasn’t. and i clearly stated what i was talking about. this is a big problem with this forum–rather than people paying attention to what people say in GD, they just make up their own debate then argue that. so congrats! you win the argument you made up–not \*all \*UFO sightings are planes. but i was talking about the ones with running/blinking lights. many have light patterns that match the layouts of known terrestrial aircraft. many other have been fully debunked as classified or experimental aircraft. there’s still not a reasonable theory as to why one should default to aliens. and that was pretty much the gist of the whole point. ---

> [@Kobal2](#): > > …it’s weird that we’re [made out of meat](http://www.youtube.com/watch?v=gaFZTAOb7IE), y’know ? :p), I thought you would be linking to the short story, itself. Instead you linked to someone who actually dramatized it. Cool Points for You! That was hilarious. Getting back to the OP’s point. No life form will evolve that uses a wavelength of EM radiation that isn’t well into it’s sun’s peak emission. No life form we’ve ever found can see a wavelength that isn’t pretty damn copious in its environment. And easily distinguishable. We _can_ pretty well say that there will never be a life-form that sees in the VHF range. Why? Because anything that could is dealing with temperatures too cold for there to be any significant selection pressure for differentiating the signals they receive, and they would have to have ‘eyes’ that actually work (i.e. are one or two meters across), in that environment. Sure. I can _imagine_ that. I can’t see how it would be _useful_ for it to come here (shit-loads of light-years) and ‘anal probe’ random rednecks. If they are here at all, they see in pretty damn near the same wavelengths. Or they wouldn’t _be_ here. ---

Again, read what \*\*you \*\*wrote. Read it again. Read it once more. All **I** was saying is that if the only element of a given UFO story is “it had lights”, or even “it had lights extremely reminiscent of the lights airplanes have”, then \*\*that \*\*is not enough to immediately assess it as an aeroplane, military or otherwise. You need more contextual data than that. Got it this time ? Now, with that in mind, and with the clarifications you’ve now added, I’m… not quite sure what it is you wish to debate. “Are specific UFOs that have been conclusively identified as planes, exhibit plane-like behaviour, are witnessed in the vicinity of an airport and are in the shape of planes, in fact, planes ?”. Well yes, yes they might just be at that. Congratulations on your keen deductive mind. “Do we have reasons to assume _a priori_ that the subset of UFOs that are planes are not in fact planes ?”, no, no we don’t, not as such, no. Once again, congratulations on passing Things We Already Know 101 with a minor in Tautology summa cum laude. Seriously, what \*is \*the debate you want to have here ? > [@](#): > > go back and re-read the OP. i asked something about blinking lighted aircraft that people call UFOs. No, you talked about blinking lights in the context of UFO sightings, of which there is a very large variety. The word “aircraft” is not present once in the OP.

Disclaimer- I don’t believe in the ET explanation for UFOS but- …some people in this thread have given some fairly sensible reasons why these things might have lights on them. Lets see if there are any more. One almost sensible idea suggested to me once was that the lights are camouflage. You can’t see the exact shape of the craft because the lights are shining in your eyes. Something like WW1 dazzle camouflage, but with lights. Another is that the lights are part of the drive phenomenon. If they turn them off they fall out of the sky. Perhaps they are waste heat radiators or something. My own ‘theory’ is that the ufonauts have forgotten where the off switch is. They’ve been flying around in these fully automated, voice-activated spacecraft for so long they’ve forgotten what most, or all, of the controls do. they don’t even know the external lights are on. ---

> [@](#): > > it has always been the first problem i find with UFO sightings: the blinking, colorful lights. even as a kid, i would think “gee, aren’t those lights safety measures for earth-only DOT compliance? are aliens really rigging up their crafts to be DOT safe?” I don’t see this as unrealistic. Assuming that aliens would have eyes or some alien equivalent, they would need running lights for the same reasons we need them. There are a lot of reasons why UFO’s as flying saucers from another planet are implausible, but this isn’t one of them, IMHO anyway. > [@](#): > > so. is there a reasonable theory why aliens would need flashing, extra-attention grabbing lights…or does the presence of blinking lights pretty much guarantee that these UFOs are 100% man-made? Either way you have to make some assumptions. You are assuming that aliens wouldn’t use lights and that they would want to hide. I’d say that’s as valid as the assumption that aliens would use running or other lights and do not want to hide. Either is equally plausible…or, equally implausible. > [@](#): > > (for the record, i believe aliens probably statistically exist but i think every UFO sighting is just some man created vehicle. there’s a reason most UFO sightings cluster around military bases…) Oh, I’m about 99% sure that most if not all alien sightings were either swamp gas reflecting Venus, some other natural phenomena or military (or even civilian) air craft of one type or another. The only reason I don’t say 100% is, well, I never think anything is 100% sure. 😉 And I DO believe that there is alien life out there…I’m, well, 99% sure of that. I’m fairly sure that there is alien life (outside of the Earth) in our own solar system (say, 60% sure), in fact. In the Galaxy? 99%. In the Universe? 99.999999999999999…% sure.
