Two alleged alien corpses were unveiled to Mexico Congress

As you probably heard by now, two alleged alien corpses were unveiled to Mexico Congress on 13 Sep 2023.
Apparently they were discovered near Cusco, Peru in 2017 in diatomite mines
One was 700 years old, and the other 1,800 years old, each with 3 fingers on each hand.
UNAM's research indicates that 30% of their DNA is "unknown"
X-rays had shown the "aliens" to have "eggs" inside and also implants of rare metals, like osmium

Jaime Maussan, journalist and ufologist said the bodies “were found buried in diatomite mines”
"These specimens are not part of our terrestrial evolution"

But some expressed their doubts about the “aliens”presented:

Ryan Graves, former lieutenant US Navy, and one of the Navy pilots who testified under oath a few months ago to the Congress about the threat of unidentified aerial phenomena (UAP) said on twitter:

" After the U.S. Congressional UFO hearing, I accepted an invitation to testify before the Mexican Congress hoping to keep up the momentum of government interest in pilot experiences with UAP. Unfortunately, yesterday’s demonstration was a huge step backwards for this issue. My testimony centered on sharing my experience and the UAP reports I hear from commercial and military aircrew through ASA’s witness program. I will continue to raise awareness of UAP as an urgent matter of aerospace safety, national security, and science, but I am deeply disappointed by this unsubstantiated stunt."

Neil deGrasse Tyson on Piers Morgan Show : "If those are aliens that would be amazing but in science you need verification from independent sources"

Brian Cox is also skeptical: "Obviously I’ve been asked about this story. My immediate response - they are way too humanoid. It’s very unlikely that an intelligent species that evolved on another planet would look like us. Secondly - send a sample off to 23andme - let alone the University down the road - and they’ll tell you within 10 minutes"
