X-ray images of enigmatic 'extraterrestrial remains' showcased at a recent Mexican congressional hearing have ignited curiosity, leaving both experts and enthusiasts pondering their source and import.

In the presence of a congress comprised of astonished officials, a UFO researcher presented two ostensibly "otherworldly" entities.

During an event he described as a "watershed" moment in front of the Mexican Congress on Tuesday, Jaime Maussan, a seasoned investigator of extraterrestrial phenomena for many years, joined forces with experts to unveil two deceased entities.

As reported by Mexican media, the experts made an astounding assertion that the bodies, which were contained in transparent enclosures and purportedly discovered in Cusco, Peru, did not belong to "our terrestrial evolution," as 30% of their genetic composition remained "unknown."

The preserved specimens, characterized by their three-fingered hands, toothless mouths, and stereoscopic vision, were scientifically confirmed to be over a millennium old, as indicated by carbon dating conducted by the National Autonomous University of Mexico (UNAM).

Online conspiracy theorists have been enthralled by the peculiar presentation, although skepticism has also arisen. The specimens were found to be covered in what appeared to be sand, an uncommon feature in fossils subjected to examination.

However, during Tuesday's testimony, while under oath, Maussan, who had previously been associated with discredited alien theories, asserted: "These specimens are not part of our terrestrial evolution [...] These aren't beings that were found after a UFO wreckage. They were found in diatom [algae] mines, and were later fossilized."

He later added: "Whether they are aliens or not, we don't know, but they were intelligent and they lived with us. They should rewrite history."

"We are not alone in this vast universe, we should embrace this reality," he said at the event.

The bodies exhibited during the gathering bore a relatively humanoid resemblance.

Nevertheless, El País pointed out that a retractable neck and a sizable skull exhibited traits that are more "typical of birds."

The presenters highlighted the additional discovery that these entities were devoid of teeth and possessed robust, lightweight bones.

In Congress, experts who exhibited alleged X-rays of the specimens informed the deputies that one of the creatures was found to be carrying 'eggs' containing embryos.

They asserted the presence of cadmium and osmium metal implants.

Osmium is considered the scarcest precious metal and one of the most uncommon elements in the Earth's crust.

Maussan referred to the event as a "landmark" moment because it signaled the initiation of an official discussion in Mexico to acknowledge the phenomenon.

He stated that experts from the National Autonomous University of Mexico (UNAM) had recently conducted radiocarbon dating on the specimens.

Numerous American and Mexican officials were present to discuss Unidentified Aerial Phenomena during the Tuesday gathering.

Harvard Astronomy Department's director, Abraham Avi Loeb, participated via video link and appealed to the Mexican government to grant permission for researchers from other nations to continue their examination of the samples.

Also in attendance was Ryan Graves, a former Navy pilot and retired director from the US Navy.

Earlier this year, Graves provided testimony regarding 'UAP' sightings and government classification.

In July, he made claims about the threat posed by UAPs to American national security.

Graves testified that while stationed off the coast of Virginia in 2014, his squadron regularly encountered unusual objects, and UFOs were considered an 'open secret' within the military.

Comparable legislative hearings, like those in Mexico, involved demands for the government to disclose relevant classified documents.

After whistleblower David Grusch's startling disclosure that individuals had been killed in a plot to conceal UFOs, the Department of Defense announced in August that a new website would be established to release officially declassified UFO-related material.

The website is currently in the process of being built, but once completed, users will be able to easily navigate through images and videos.

Federal officials released a statement about the website in which they asserted that its launch exemplifies the Defense Department's dedication to providing "transparency with the American people" regarding their research on UAPs, the government's terminology for UFOs.

During Tuesday's gathering in Mexico, Robert Salas, a retired USAF lieutenant, addressed the stigma linked to UAP sightings.

He said: "As we speak, our sky is full of [UAPs], whose existence is not reported enough."

"Sightings are not rare or isolated, they are routine. It is a stigma of the [UAP] and poses a powerful challenge to national security," he said, as reported by Infobae.

The audience at the hearing witnessed UAP footage, including video clips of lights hovering above the clouds that were captured by a fighter jet.

Others shared stories of experiencing unusual events while working across Mexico.

All those present were requested to rise and take an oath affirming the veracity of the statements presented.

In 2015, Jaime Maussan revealed a second mummified body, asserting that it belonged to an extraterrestrial being.

The body was found near the Nazca Lines, a collection of geoglyphs in Peru varying in size from 50 to 1200 feet.

There have been speculations that the sentences themselves might be of extraterrestrial origin because they lack a clear origin story.

Nevertheless, the accusation was ultimately debunked, as reported in a Snopes investigation.

Instead, it was claimed that the remains of a human child were found.

Subsequently, it was established that the five bodies unearthed in Peru in 2017 were, in fact, those of human children.
