Secret UFO civilization, aliens could be here on Earth already: Harvard scientists

Aliens might be living among us, Harvard academics are suggesting, perhaps residing in an advanced technological civilization deep underground or, maybe, in a base inside the moon.That’s right — a new paper by researchers at Harvard University’s Human Flourishing Program posits that “unidentified anomalous phenomena” (UAP), more commonly referred to as UFOs and extraterrestrial beings, could be living underground, on the moon or even walking among humans.And, yes, the authors are fully aware the report will raise eyebrows and likely be met with skepticism by the scientific community, but encourage “consideration in a spirit of epistemic humility and openness.”The new study, titled The cryptoterrestrial hypothesis: A case for scientific openness to a concealed earthly explanation for Unidentified Anomalous Phenomena, provides four possible explanations for the ongoing “concern regarding UAPs.”“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 civilisations from elsewhere in the cosmos),” they said.“However, there is also a third minority class of hypothesis: an unconventional terrestrial explanation, outside the prevailing consensus view of the universe.”The authors, Tim Lomas (Harvard University), Brendan Case (Harvard University) and Michael Paul Masters (Montana Tech of the University of Montana), make the case for the possibility of so-called “cryptoterrestrials” to explain unidentified and unexplainable observations made around the world each year.They suggest a number of “cryptoterrestrial” hypotheses (CTH) to argue that aliens could walk among us, including:The authors, however, do
