MEXICO CITY, Mexico, (AFP) – The alleged bodies of two “non-human” beings were presented during a congressional hearing in Mexico, generating a mixture of surprise, disbelief and ridicule on social media on Wednesday.

The purported mummified remains were exhibited in two small display cases on Tuesday — the first time the Mexican Congress has officially addressed the issue of possible extraterrestrial life.

The alleged corpses, which had a grayish colour and a human-like body form, were brought by Jaime Maussan, a controversial Mexican journalist and researcher who reported finding them in Peru in 2017.

“They are non-human beings. We don’t want to call them extraterrestrials because we don’t know,” Maussan said during the session called by ruling party lawmaker Sergio Gutierrez, who defended the event as being in the “public interest.”

Maussan cited carbon dating analysis by the National Autonomous University of Mexico that he said showed “these beings are around 1,000 years old.”

Gutierrez asked the speakers to swear to tell the truth during the hearing.

He said Maussan requested the session after a US congressional committee was told by a former intelligence official in July that humans were not alone in the universe and American authorities were covering up the evidence.

In May, the US space agency NASA held its first public meeting on the issue, and urged a more rigorous scientific approach to clarify the origin of so-called unidentified anomalous phenomena (UAPs).

The Mexican hearing generated both astonishment and mockery, including jokes accompanied by photos of the alien creature in the movie “ET.”

The event “shows the contempt that this country has for science,” one user wrote on the social media platform X, formerly called Twitter.

Others shared videos of the event with the words “The Martians have arrived,” while there was a tongue-in-cheek call for Maussan to be named “president of intergalactic relations.”
