A Mexican Congressional hearing on UFOs in September was invaded by evidence of alleged alien corpses, wheeled in and unveiled to the Congress and the press by Mexican journalist and "ufologist" Jaime Maussan.
This latest stunt came about six years after Maussan made similar claims in Peru; the country's prosecutor found at the time that the alien corpses were actually "recently manufactured dolls, which have been covered with a mixture of paper and synthetic glue to simulate the presence of skin.”

Those apparently synthetic bodies were never shown to the public, so it remains unclear if the corpses shown to the Mexican Congress are the same. Still, the demonstration garnered a fair amount of criticism, with UFO whistleblower and former Navy pilot Ryan Graves calling the demonstration "a huge step backwards for this issue."
Famed astrophysicist Neil DeGrasse Tyson, though encouraged by an anomaly that can now be investigated, was additionally skeptical of the design of the so-called alien lifeforms.
"These are very humanoid. Most life on earth with whom we have DNA in common does not look humanoid," Tyson said on The Late Show with Stephen Colbert, noting the figures' distinctly human arms, legs, shoulders, eyes, mouth, nose and fingers. "We have DNA in common with a banana, with oak trees, with worms, with lobsters; for an alien from another planet to be this humanoid ... that's odd."
Still, Tyson said that this Mexican alien demonstration is "better than what happened in our Congress where the guy has aliens in a locked box. That's not useful to scientists."
Former U.S. intelligence officer David Grusch told NewsNation in June that UFOs are more common than people might think, and further, that the U.S. government is in possession of crashed alien spacecraft, complete with the dead bodies of their pilots.

In July, he, Graves and former Navy commander David Fravor testified to their first-hand experiences with UFOs.
"If everyone could see the sensory and video data I witnessed," Graves said at the time, "our national conversation would change."
Dr. Sean Kirkpatrick, an analyst with the Department of Defense's Anomaly Resolution Office, said in April that the government has "no credible evidence" of alien activity or technology on Earth.
"The Universe brims with mystery. Just because you can't explain something doesn't mean you can explain it," Tyson said, criticizing arguments that UFOs are evidence of extra-terrestrial life. "If you see something in the sky that you cannot explain and you call it a UFO, once you say 'I don't know what it is,' you don't have the argument rights to say 'I do know what it is.'"
"We live in the world of the unexplained."
