A new study conducted by social science researchers from Harvard suggests that aliens could already be present on Earth.

The study suggests that extraterrestrial life forms could be dwelling underground or in the Moon. It also suggests that unidentified anomalous phenomena (UAP) and UFOs could be evidence of these aliens.

Unconventional UAP Explanation

The study, which is yet to be peer-reviewed, suggests an unconventional UAP explanation. Authors of the study are from the Human Flourishing Program of Harvard University. The program researches factors that affect the flourishing and well-being of humans.

UAP generally refers to any phenomenon or object that cannot be immediately explained or identified by natural or human-made sources. The authors note that the "A" in the term represents anomalous, rather than "aerial." This is due to how some UAP can also travel underwater.

These UAP have been reported in different forms, including discs, spheres, triangles, and other shapes. They range from being tiny orbs to big crafts. Several of these UAPs show maneuvers and flight patterns that go against typical aerodynamics.

Last summer, David Grusch, an Air Force veteran, caused a storm after claiming that a confidential US military program discovered the wreckage of several unidentified aerial craft that were fully intact. Some of them reportedly contained dead pilots that were non-human.

Moreover, the Office for the Director of National Intelligence also issued a 2023 report that found that 510 UAP sightings were identified in 2022. Among these, 171 were thought to have appeared in order to show odd performance capacities or flight characteristics.

The Harvard researchers said that in order to explain such phenomena, there are typically two classes of hypotheses. These include an extraterrestrial explanation or a conventional terrestrial explanation.

However, they note that there could be a third hypothesis that covers an unconventional terrestrial explanation. This would come outside the prominent consensus regarding how the universe is seen.

Such a claim, called the ultraterrestrial hypothesis, covers a cryptoterrestrial hypothesis subset. This refers to the idea that UAP could just be reflections of activities performed by intelligent beings stealthily hiding on Earth or in its nearby environments, such as the Moon. These beings could even be walking among humans.

The researchers noted four theories regarding the possibility of humans living alongside humans. The first one suggests that an ancient human civilization that could be more technologically advanced was able to secretly survive.

The second one proposes that a technologically advanced civilization that was non-human could have secretly evolved on Earth. It could have been created by a hominid that was ape-like or some intelligent and unknown dinosaurs.

The third theory holds that humans or aliens from the future could be secretly living on Earth, while the fourth one suggests that some magical cryptoterrestrials that are akin to earthbound angels could be present.

While most scientists may hold skepticism towards such ideas, these could be the nature of some UAPs that they argue that such possibilities should not be altogether dismissed.

However, most field experts do not think that UAP and UFOs reflect extraterrestrial activity.
