The human quest to look for neighbours in the nearby galaxies is never-ending, and the idea that we might not be alone in the universe has been discussed for generations.Scientists and varied research organisations have spent years looking for signs of life beyond Earth, watching the skies, sending out radio signals, and exploring distant planets. But despite all the effort, the big question still remains, “Do aliens actually exist?”A theory from researchers at Harvard University suggests we may have been looking in the wrong direction all along. What if aliens aren’t in the far corners of space but right here on Earth, living among us?This isn’t a movie plot, but an academic proposal from Harvard’s Human Flourishing Program. It challenges our assumptions about alien life and invites us to have new perspectives about this theory.
What does the study propose
According to the study, so-called extraterrestrial beings, or “cryptoterrestrials,” could be living underground, hidden on the Moon, or even among humans in disguise.Although the study has not yet been peer-reviewed, it focuses on the cryptoterrestrial hypothesis. According to the paper, “The author became increasingly aware of the depth of evidence and theory that also tentatively supports another extraterrestrial explanation: the ‘cryptoterrestrial’ hypothesis (CTH) – our focus here – which holds that UAP may reflect activities of NHIs concealed here on Earth (e.g., underground) and its environs.”In simpler terms, the researchers are suggesting that unidentified aerial phenomena or UAPs, earlier known as UFOs, could be connected to hidden non-human intelligences (NHIs) that already reside on Earth or nearby.

According to the paper, the researchers suggest that these hidden beings, called cryptoterrestrials, could come in four different forms. First, there are Human Cryptoterrestrials or the survivors of an ancient, advanced human civilization that was mostly wiped out long ago but still exists secretly. Another suggestion is that there are Hominid or Theropod Cryptoterrestrials, which could be intelligent non-human species like ape-like creatures or even evolved dinosaurs that learned to live in hiding, possibly underground.A third type is Former Extraterrestrial or Extratempestrial Cryptoterrestrials beings that may have either come from another planet or from Earth’s future, choosing to remain hidden on Earth or the Moon APart from these, there are the Magical Cryptoterrestrials, described more like mythical beings such as fairies, elves, or nymphs, that don’t rely on technology but instead interact with humans in mysterious, magical ways.

The theory still remains under skepticism
The researchers admit their theory may be met with skepticism, stating, “This paper is likely to be regarded skeptically by most scientists,” but they openly support open-mindedness, “We hope to help normalize rigorous scientific analysis of anomalous phenomena and encourage the scientific community to consider this data with a spirit of epistemic humility and openness.”This study comes in the wake of several claims by former US intelligence officials about government knowledge of non-human technology, as an addition to the public’s growing interest in UAPs.
