Of these, 171 were considered to "appear to have demonstrated unusual flight characteristics or performance capabilities, and require further analysis." "Hypotheses for such phenomena tend to fall into two classes: a conventional terrestrial explanation (e.g., human-made technology), or an extraterrestrial explanation (i.e., advanced civilizations from elsewhere in the cosmos)," the Harvard researchers wrote in the new paper. "However, there is also a third minority class of hypothesis: an unconventional terrestrial explanation, outside the prevailing consensus view of the universe," they wrote. "This is the ultraterrestrial hypothesis, which includes as a subset the 'cryptoterrestrial' hypothesis, namely the notion that UAP may reflect activities of intelligent beings concealed in stealth here on Earth (e.g., underground), and/or its near environs (e.g., the moon), and/or even "walking among us" (e.g., passing as humans)." In the paper, the researchers discuss four theories of how aliens may be living alongside us, the first of which—the human cryptoterrestrials theory—suggests that there may be an ancient human civilization much more technologically advanced than our own that has somehow survived in secret. The second theory is that there is a technologically advanced non-human civilization that evolved on Earth in secret, created by an ape-like hominid or some "unknown, intelligent dinosaurs." The third suggests that there are aliens or humans from the future that live on the Earth in secret, and the fourth suggests there are "magical cryptoterrestrials" akin to "earthbound angels," which the researchers compare to "fairies, elves, nymphs." "The principal weakness of \[the final theory\], by contrast, is its utter strangeness, particularly for readers schooled to limit themselves to modes of explanation within the bounds of, say, the standard model of physics," the researchers write in the paper. "While belief in extraterrestrials is tenable, belief in (something like) fairies is simply not a live option for many scientists. "Although this idea is likely to be regarded skeptically by most scientists, such are the nature of some UAP that we argue this possibility should not be summarily dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness." However, the majority of experts in the field do not believe that UFOs or UAP are evidence of extraterrestrial activity. "I think it highly, highly unlikely that any other civilisation could have been living on Earth or the Moon undetected the whole time—I just don't think that sounds feasible. In all honesty, I think UAPs will end up having interesting but natural explanations; that's something I've seen time and time again in my life," Jonti Horner, an astrophysics professor at the University of Southern Queensland, Australia, told Newsweek. "For decades there were reports of strange phenomena above thunderstorms being reported by pilots, which were roundly derided. Nowadays, we know of imps and sprites—electrical phenomena flashing upward from highly energetic storms to the ionosphere," he said. "I'm not an expert in them, but they're a really good example of how something that was originally in the UFO/UAP domain transitioned to mainstream science once we got enough data to properly understand it. I think the great majority of the current UAPs will go the same way—that with better data we will eventually work out what they are, and they will turn out to be of natural origin. "That's still really exciting, though, as it means we still have more to learn about the Earth and the cosmos, which, in all honesty, is a core part of being a scientist. There's always another secret to uncover." *Do you have a tip on a science story that Newsweek* should be covering? Do you have a question about UAPs?

"The principal weakness of \[the final theory\], by contrast, is its utter strangeness, particularly for readers schooled to limit themselves to modes of explanation within the bounds of, say, the standard model of physics," the researchers write in the paper. "While belief in extraterrestrials is tenable, belief in (something like) fairies is simply not a live option for many scientists. "Although this idea is likely to be regarded skeptically by most scientists, such are the nature of some UAP that we argue this possibility should not be summarily dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness." However, the majority of experts in the field do not believe that UFOs or UAP are evidence of extraterrestrial activity. "I think it highly, highly unlikely that any other civilisation could have been living on Earth or the Moon undetected the whole time—I just don't think that sounds feasible. In all honesty, I think UAPs will end up having interesting but natural explanations; that's something I've seen time and time again in my life," Jonti Horner, an astrophysics professor at the University of Southern Queensland, Australia, told Newsweek. "For decades there were reports of strange phenomena above thunderstorms being reported by pilots, which were roundly derided. Nowadays, we know of imps and sprites—electrical phenomena flashing upward from highly energetic storms to the ionosphere," he said. "I'm not an expert in them, but they're a really good example of how something that was originally in the UFO/UAP domain transitioned to mainstream science once we got enough data to properly understand it. I think the great majority of the current UAPs will go the same way—that with better data we will eventually work out what they are, and they will turn out to be of natural origin. "That's still really exciting, though, as it means we still have more to learn about the Earth and the cosmos, which, in all honesty, is a core part of being a scientist. There's always another secret to uncover." *Do you have a tip on a science story that Newsweek* should be covering? Do you have a question about UAPs?
