Aliens could be 'walking among us' in secret bases on Earth, Harvard scientists suggest

I know what you're thinking: "We've heard it all before."

But a group of Harvard scientists have explained why they think aliens are 'walking among us'.

In their new study - titled 'The cryptoterrestrial hypothesis: A case for scientific openness to a concealed earthly explanation for Unidentified Anomalous Phenomena' - three scholars have given their take on the UFO (or UAP) phenomena.

UAP stands for 'Unidentified Anomalous Phenomena', incase you were wondering.

This comes amid whistleblower claims that the government are allegedly keeping UAPs and aliens, from us.

Former Air Force intelligence officer Major David Grusch told US Congress last July that the government are 'absolutely' in possession of UAPs.

Meanwhile, Defence Department spokeswoman Sue Gough said investigators have not discovered 'any verifiable information to substantiate claims that any programmes regarding the possession or reverse-engineering of extra-terrestrial materials have existed in the past or exist currently'.

That being said, in the new study, which was published last month, authors Tim Lomas (Harvard University), Brendan Case (Harvard University) and Michael Paul Masters (Montana Tech of the University of Montana) provided us with three 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 scientists put forth the theory of an 'ultraterrestrial hypothesis', which includes as 'a subset the 'cryptoterrestrial' hypothesis', adding: "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)."

These subsets range from 'human cryptoterrestrials', who could be a 'technologically advanced' civilisation that was 'destroyed long ago' but has 'continued to exist in remnant form' to 'descendants of unknown,

intelligent dinosaurs'.

The paper mentions a few places of speculation around 'prominent hotspots' for UAP, including an 'Alaskan Triangle' in a 'sparsely populated area between Anchorage and Juneau in the south to Utqiagvik', and submerged stone structures in Yonaguni Jima in Japan.

They also argue that while this idea 'is likely to be regarded sceptically by most scientists', due to the nature of some UAP, this possibility 'should not be summarily dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness'.

The study has yet to be peer-reviewed.

This ties with in NASA's recent statement that they are still yet to witness any alien-life in space.

Last year, NASA said: "One of NASA's key priorities is the search for life elsewhere in the universe, but so far, NASA has not found any credible evidence of extraterrestrial life and there is no evidence that UAPs are extraterrestrial.

"However, NASA is exploring the solar system and beyond to help us answer fundamental questions, including whether we are alone in the universe."

I mean if aliens were among us, they would say that wouldn't they?
