In June, David Grusch, a former U.S. intelligence officer, told NewsNation that UFOs are a regular presence in Earth's skies, adding that the U.S. government is in possession of crashed spacecraft complete with the bodies of their pilots.
In late July, Grusch and two other whistleblowers — former Navy pilot Ryan Graves and former Navy commander David Fravor — testified before a congressional hearing meant to help Congress understand how to respond to these sightings of strange aircraft, dubbed UAPs by the government.

And in September, Mexico's Congress held its own hearing on UFOs, where a Mexican journalist displayed the bodies of two supposed "non-human beings," each with three-fingered hands and elongated heads.
The journalist and "ufologist," Jaime Maussan, made similar claims in Peru in 2017. The country's prosecutor found that the bodies shown at the time were not bodies at all, but "recently manufactured dolls, which have been covered with a mixture of paper and synthetic glue to simulate the presence of skin.”
Those corpses, however, were never shown to the public; it remains unclear if the bodies Maussan unveiled last week are the same ones from 2017.
Graves, who additionally agreed to testify before the Mexican Congress, was "deeply disappointed by this unsubstantiated stunt."
"Yesterday's demonstration was a huge step backwards for this issue," Graves said.
But famed astrophysicist Neil DeGrasse Tyson, speaking to CNBC, had a different take on the matter.
"The aliens in Mexico, I'm glad they put them forth. Now, share that with other scientists," he said, "so that we can decide, is it a hoax, is it verified. That's how science progresses. Not by the lone wolf saying 'I have the thing that nobody else has and it's real.'
We've got to double-check that."

The alien unveiling came a day before NASA released the results of a year-long independent study into UFOs, where NASA Administrator Bill Nelson noted, "The top takeaway from the study is that there is a lot more to learn."
"The team did not find any evidence that UAP have an extra-terrestrial origin," he said. "But we don't know what these UAP are."
The report did not attempt to uncover the truth behind previous UFO sightings; rather, it made a series of recommendations to NASA to improve its data capture and curation methods as the agency moves to increase its study of UFOs.
In response to CNBC host Brian Sullivan's stated belief that the Universe, being as large as it is, must house some sort of extra-terrestrial life somewhere, Tyson said: "Everyone who has studied the problem agrees with you."
"The Universe is vast. The number of stars is huge. Planets around the stars is huge. The ingredients of life itself are everywhere," Tyson said. "We're made out of the most common ingredients in the Universe. It's a different question to say 'are these lights and objects in the sky visiting, intelligent aliens?'
We don't know what they are. Just because you don't know what it is doesn't mean you know what it is."
