The UFO Library: Humanoid encounter
Nazca Mummies (2023)
Ufologist Jaime Maussan presents purported alien mummies to Mexican Congress; later definitively proven fraudulent by forensic analysis.
The Presentation
On September 12, 2023, Mexican journalist and longtime ufologist Jaime Maussan presented two mummified humanoid bodies to the Chamber of Deputies of the Mexican Congress during a formal hearing on Unidentified Anomalous Phenomena (UAP). The bodies, displayed in sealed glass cases, were small and skeletal with characteristics matching popular culture depictions of extraterrestrial "grey" aliens: elongated heads, three-fingered hands, and large almond-shaped eye sockets.
Claims and Alleged Origin
Maussan claimed the specimens were discovered in Peru near the ancient Nazca Lines in 2017 and that they were approximately 1,000 years old. He testified under oath that the remains "are not part of our terrestrial evolution" and that approximately one-third of their DNA could not be identified or matched to known species. Maussan cited carbon dating performed by Mexico's National Autonomous University (UNAM) and stated the bodies represented genuine non-human intelligence.
The presentation attracted significant international media attention, with footage widely distributed across news outlets, social media, and documentary channels.
Scientific Rejection
Within days, Mexico's UNAM Institute of Physics issued a formal statement disassociating itself from Maussan's claims, clarifying that no comprehensive carbon dating analysis was performed on the specimens by the institution. The institute stated that Maussan's interpretations "do not make sense" from a scientific perspective.
In January 2024, the Institute of Forensic Legal Medicine of Peru's Public Ministry conducted a definitive examination of the seized mummies. Their forensic analysis concluded the specimens were fraudulent: one skull was identified as belonging to a terrestrial quadruped mammal, the skeletal framework was composed of bird and human bones, and the components were assembled using modern synthetic adhesive—proving they could not be ancient pre-Hispanic artifacts, let alone extraterrestrial remains.
Legacy and Context
This incident exemplifies the ongoing tension between fringe UFO believer communities and mainstream scientific skepticism. Despite being presented to a national legislature by a prominent figure in UFO research with decades of credibility in that community, the mummies were rapidly and conclusively debunked through standard forensic methodology. The case highlights how extraordinary claims—even when backed by high-profile advocates and presented in official settings—require rigorous verification before acceptance.
