Within hours of the research paper being published, it appeared to be removed from the internet. SCNR, however, retained a a pdf copy of the full report, which delves into various hypotheses surrounding Unidentified Anomalous Phenomena (UAP), traditionally explained by either human technology or advanced extraterrestrial civilizations. The study finds that discourse on this subject is typically dominated by two classes of explanations: 1) conventional terrestrial origin (human technology), and 2) extraterrestrial origin (advanced civilizations from somewhere else). Yet, many UAP observers are now considering an other sets of theories, one known as the “cryptoterrestrial” hypothesis (CTH). This centers on the possibility that UAP could involve various forms of non-human intelligence (NHI) already present on earth who have been living alongside us in stealth. As described in the paper, some of these entities could be living underground, while others could be walking among us “disguised convincingly as regular humans.” UAPs have re-emerged to the forefront of public consciousness amid multiple disclosures by whistleblowers in recent years who have claimed that the U.S. government is in possession of multiple non-terrestrial crafts, and the biological material of the pilots of those craft. The Harvard paper could contribute further mystery and allure to the discussion with its suggestion that not only could non-terrestrial intelligent beings exist, but they may be living and working among us daily. Researchers cite the potential for four different CTHs, all of which “would involve entities existing in stealth during recent human history – and possibly even before the emergence of Homo sapiens in some cases.”A new study from Harvard University's Human Flourishing Program proposes that aliens might be walking among us disguised as human beings.
In an email to SCNR, Tim Lomas, one of the paper's authors, confirmed that an updated version of the paper has since been uploaded.

CTH1: Human cryptoterrestrials. A technologically advanced ancient human civilization that was largely destroyed long ago (e.g., by flood), but continued to exist in remnant form. CTH2: Hominid or theropod cryptoterrestrials. A technologically advanced non-human civilization consisting of some terrestrial animal which evolved to live in stealth (e.g., underground), perhaps a hominid, or alternatively a species much more distantly related to us (e.g., descendants of unknown, intelligent dinosaurs). CTH3: Former extraterrestrial or extratempestrial cryptoterrestrials. Extraterrestrial aliens or our intertemporal descendants who “arrived” on Earth from elsewhere in the cosmos or from the human future, respectively, and concealed themselves in stealth. CTH4: Magical Cryptoterrestrials. Entities which are less like homegrown aliens and more like earthbound angels, relating to the world inhabited by humans in ways that (at least from our present perspective) are less technological than magical, who are known in European languages by names like fairies, elves, nymphs, etc. “All four CTHs are far-fetched on their face,” the researchers admit. “We entertain them here because some aspects of UAP are strange enough that they seem to call for unconventional explanations.” According to the paper, “most investigations of UAP to-date have focused on the [extraterrestrial hypothesis] ETH, which does have several lines of evidence in its favor.” ETH, however, does not exhaust all of the possible sightings of UAP throughout the world, the paper explains. The researchers state that while a cryptoterrestrial hypothesis may be “exceedingly improbable,” it “should nevertheless be kept on the table as we seek to understand the ongoing empirical mystery of UAP.”
