The creatures, with their tiny bodies, three-fingered hands and elongated heads, looked like something right out of a Hollywood alien invasion blockbuster movie.
But if UFO researcher Jaime Maussan is to be believed, the remains he presented to Mexican lawmakers are the real thing.
Some of Maussan's prior claims have proven to be false but earlier this week, the famed journalist and self-proclaimed UFO expert appeared before Mexican lawmakers, where he presented the remains of what he claimed were two ancient "non-human" alien corpses. The bodies, he testified, were retrieved in 2017 from Cusco, Peru before radiocarbon dating revealed them to be up to 1,800 years old.
Maussan's wild claims, which he presented without third-party evidence, came during a Tuesday congressional hearing in Mexico about UFOs, now referred to by the U.S. government as UAP, short for unidentified anomalous (or aerial) phenomena.
"This is the first time (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," Maussan testified in Spanish.
The small mummified specimens that Maussan alleges are extraterrestrials were brought out in two glass display cases for lawmakers to observe.
The hearing was to debate language on UAP in the Aerial Space Protection Law. If the language is approved, Mexico would become the first nation to formally acknowledge the presence of alien life ever existing on Earth, the Reuters news agency said, citing local media.
