Scientists in Mexico are pulling back the curtain on what some believe are aliens, and the remains of "non-human" beings were put on display.
Two small mummified specimens were presented Tuesday at Mexico's first public congressional hearing on Unidentified Anomalous Phenomena (UAPs), also known as UFOs.
Displaying two mummified bodies he claimed to be not from Earth, journalist and UFO researcher Jaime Maussan and other experts proposed that the Mexican Chamber of Deputies recognize UAPs, to guarantee airspace security and to allow it to be studied. The shriveled bodies with shrunken, warped heads left those in the chamber aghast and quickly kicked up a social media fervor.
"It's the queen of all evidence," Maussan claimed. "That is, if the DNA is showing us that they are non-human beings and that there is nothing that looks like this in the world, we should take it as such." But he warned that he didn't want to refer to them as "extraterrestrials" just yet.
The apparently desiccated bodies date back to 2017 and were found deep underground in the sandy Peruvian coastal desert of Nazca. The area is known for gigantic enigmatic figures scraped into the earth and seen only from a birds-eye-view. Most attribute the Nazca Lines to ancient indigenous communities, but the formations have captured the imaginations of many.
Maussan said it was a clear demonstration that the presented bodies were non-human specimens, and that researchers could prove that the DNA of the two mummies did not belong to human beings.
"This is the first time it (extraterrestrial life) is presented in such a form and I think there is a clear demonstration that we are dealing with non-human specimens that are not related to any other species in our world and that any scientific institution can investigate it," he said.
X-rays of the "aliens" were also shown during the hearing, and experts say one of the bodies had eggs inside.
Congressman Sergio Gutiérrez Luna of the ruling Morena party, made it clear that Congress has not taken a position on the theses put forward during the more than three-hour session. Believing or not was up to each member of the legislative body, but those who testified had to swear an oath to tell the truth.
Gutiérrez Luna stressed the importance of listening to "all voices, all opinions" and said it was positive that there was a transparent dialogue on the issue of extraterrestrials.
Earlier this year, a former U.S. intelligence community official testified on an alleged covert government program to recover and reverse engineer crashed alien spacecraft.
David Grusch, a member of a previous Pentagon office tasked with investigating UAPs, said he was informed of the alleged multi-decade program through his official duties, but was denied access to additional information.
The Pentagon said in June it hadn't found "any verifiable information to substantiate" the claims about crashed alien spacecraft.
The remarks came during a bipartisan hearing held by the House Oversight Committee's national security subcommittee. The three witnesses included Grusch, David Fravor, a former commanding officer in the U.S. Navy, and Ryan Graves, executive director of Americans for Safe Aerospace.
Members of both parties stressed the need for greater clarity on UAPs. Many voiced concerns that unidentified aerial objects pose to national security.
