Scientists have called on Mexico to make recently presented 'non-human corpses' available to the international science community for further research.
Mexican journalist and so-called "ufologist" Jaime Maussan presented the alien-like remains during the country’s first-ever UFO hearing as apparent proof of "non-human beings".
The presentation has been met with mixed reactions, with some experts describing it as an "unsubstantiated stunt".
"Unfortunately, yesterday’s demonstration was a huge step backwards for this issue," Ryan Graves, the executive director of Americans for Safe Aerospace said on social media.
A day after Mexico’s UFO hearing, scientists from NASA gathered for a similar reason.
The US space agency today released a 33-page independent report it commissioned looking into UFOs, or as they call them Unidentified Anomalous Phenomena (UAPs).
Speaking at a press conference, theoretical astrophysicist David Spergel was asked about Mexico’s non-human corpses.
"This is something that I know I have only seen on Twitter," he said, "when you have unusual things, you want to make data public".
One of the key findings from the independent research which Spergel contributed to was the need for "science-based" approaches, instead of "sensational" reporting.
He’s calling on the Mexican Government to make samples of the alleged non-human beings available to the global scientific community.
"I think of this as like NASA has one of the most valuable samples from outer space: lunar rocks. What do we do? Make them available to any scientist who wants to work on this."
"We don’t know the nature of those samples that were shown in front of us".
NASA's administrator Bill Nelson says the agency still has no evidence that researched UAP have extraterrestrial origins.
"Despite numerous accounts and visuals, the absence of consistent, detailed and curated observations means we do not presently have a body of data needed to make definitive, scientific conclusions about UAP," the report states.
Nelson said NASA's mission "is to find out the unknown", and he promised transparency in any discoveries.
"Whatever we find, we’re going to tell you," he said.
