Nazca / Peru "Alien Mummies" documented-hoax
On 12 September 2023 the Mexican ufologist Jaime Maussan presented two
small, three-fingered, elongated-skull "non-human" bodies to a hearing of
Mexico's Chamber of Deputies, testifying under oath that they were
~1,000-year-old beings "not part of our terrestrial evolution." Scientists
rejected the claims immediately, and on 12 January 2024 forensic
archaeologist Flavio Estrada of Peru's Institute of Legal Medicine
declared the specimens dolls assembled from terrestrial animal and human
bones with modern synthetic glue — a fraud, not a discovery.
The Nazca mummies are the corpus's reference fabrication and its sharpest
study in institutional credulity. A hoax was presented under oath to a
national legislature, given the procedural trappings of testimony, and
lent apparent scientific cover by a Mexican Navy medical official — before
forensic science resolved it. It is the apotheosis of Jaime Maussan's
decades-long pattern (the 1991 eclipse, the 2015 Roswell slides, the 2017
first Nazca mummies), and it directly damaged the serious UAP conversation
— the credible Navy witness Ryan Graves called it "a huge step backward...
an unsubstantiated stunt." It is the case that marks where spectacle and
evidence part ways.
Timeline
2017-07
The bodies surface from the Nazca/Palpa region of Peru, reportedly via
huaqueros (tomb robbers) looting genuine pre-Columbian graves. The
largest specimen, "Maria," is promoted by Thierry Jamin's Inkari-Cusco
institute and streamed by the U.S. company Gaia.com; Maussan leads a
July 2017 reveal. Anthropologist Andrew Nelson and Peruvian researchers
soon conclude the bodies are manipulated real human remains with a
coating "added afterward to hide the manipulations."

2021-10
Earlier Peruvian forensic work (reported by El Comercio / Infobae) finds
the "skin" is adhesive, plant fiber, pulped paper and rubber; animal
skulls have their snouts cut off; X-rays show bones artificially joined
without proper anatomical articulation.

Maussan displays two small bodies (grayish, ~1 m tall, three fingers per
hand, elongated heads) in sealed cases before the Chamber of Deputies,
in Mexico's first congressional UAP event; testimony is given under
oath. Within two days UNAM distances itself and astronomers Antigona
Segura and Julieta Fierro publicly dismiss it; Ryan Graves condemns it.

Peruvian customs intercept doll-like figures (plus a separate
three-fingered hand) in a box at DHL offices at Lima's airport, en route
to a Mexican recipient.

At the Lima archaeology museum, Flavio Estrada of the Institute of Legal
Medicine / Public Prosecutor's office declares the figures "dolls
assembled with bones of animals from this planet, with modern synthetic
glues," and "a fraud" — "They are not extraterrestrials, they are not
intraterrestrials, they are not a new species, they are not hybrids."
Pharmaceutical chemist Ernesto Avalos performed the materials analysis.

2024-2025
Peru's Nasca prosecutor pursues cultural-heritage crimes; the looter who
supplied the remains is reportedly sentenced (~4 years' conditional
imprisonment plus a fine), under appeal. No peer-reviewed evidence
supports the non-human claim through June 2026; scientifically the case
is closed, though Maussan continues to promote the bodies.

- Flavio Estrada — Forensic archaeologist at Peru's Institute of Legal Medicine and Forensic Sciences; led the analysis rank at time: · later: Delivered the 12 Jan 2024 verdict — dolls of terrestrial bones and modern glue; 'science, not pseudo-science' role: the forensic resolution
- Jose de Jesus Zalce Benitez — Director of the Scientific Institute for Health of the Mexican Navy; asserted at the hearing that 'these bodies have no relation to human beings' rank at time: role: the apparent military-scientific cover that lent the show legitimacy
- Sergio Gutierrez Luna — Morena (ruling-party) lawmaker who convened the September 2023 hearing and administered the oath rank at time: role: the institutional legitimacy the event borrowed
- Ryan Graves — Former U.S. Navy F/A-18 pilot and credible 2023 congressional UAP witness rank at time: · later: Criticized the Mexican event as 'a huge step backward... an unsubstantiated stunt', defending evidence-based UAP work role: the voice of the serious UAP field distancing itself
Object — reported
shape
two small humanoid figures with grayish, shriveled skin, elongated / conical crania, large snouts, and three fingers and three toes; thin bodies with ribcages articulated at the sides and strangely jointed limbs
size
no more than ~1 m (~3.3 ft) tall
surface features
a simulated 'skin' of paper, plant fiber, rubber and synthetic glue over assembled bones
observed behaviors
- presented as ~1,000-year-old non-human beings, with claims of 'unknown' DNA and osmium/cadmium content and 'eggs' on X-ray
- forensically determined to be made of bird and other animal bones, with a skull from a four-legged Earth mammal (one head described as a deteriorated llama braincase)
- a separately seized three-fingered hand found to be hand-made 'very poorly' from human bones joined with a metal plate, cotton, and adhesive
- the presence of modern synthetic glue ruling out any pre-Hispanic origin
Theories that invoke this case (3)
The claim the bodies were marketed under — authentic non-human beings.
The corpus records that this reading has no independent scientific
support and is directly contradicted by forensic analysis; it is
invoked by the ETH only as the claim, not as evidence.
The reading of the episode as manufactured spectacle: a fabrication
given the trappings of legislative testimony and military-scientific
cover, generating global headlines before the forensic resolution — a
case study in how a hoax borrows institutional legitimacy.
The cultural reading: how media incentive, a credulous hearing, and a
practiced promoter convert looted archaeology into a worldwide 'alien'
story — and how that spectacle damages serious inquiry.
Theories that do NOT invoke this case — and why
the physical material is fully explained as assembled terrestrial bones and modern glue — there is no anomalous material
though the bodies were marketed as ancient non-human remains, they are forensically terrestrial assemblies — no archaeological anomaly to explain
no phenomenology of any kind — a manufactured object presented as a body
Conventional explanations advanced — and their status
Deliberate fabrication — dolls assembled from looted real bones plus animal bones, bound with modern synthetic glue
proponents: Flavio Estrada / Peru's Public Prosecutor (2024) · Andrew Nelson (2018) · Guido Lombardi · the World Congress on Mummy Studies
The established forensic consensus. Corroborated across 2017-2021 analyses and the 2024 Public Prosecutor's team: genuine pre-Columbian human bones plus bird/mammal bones, disguised with paper/fiber/rubber 'skin', bound with modern glue. This is the case's settled explanation.
Authentic ~1,000-year-old non-human beings
proponents: Jaime Maussan
Rejected. Unsupported by any independent scientific body; the institutions Maussan invoked (UNAM) explicitly disavowed his conclusions, and forensic analysis directly contradicts it. The 'unknown DNA' framing reflects normal degradation/contamination — Peru's DNA testing found the material 100% human.
Where further investigation has leverage
- Essentially settled. The remaining loose ends are investigative and legal, not scientific: the full chain of custody — who assembled which specimens, and when — across the multiple bodies promoted since 2015.
- Complete adjudication of the Peruvian cultural-heritage and trafficking prosecutions (some convictions reported, under appeal).
- Nothing in the peer-reviewed literature supports the non-human claim, and no credible new evidence has emerged through June 2026; scientifically the case is closed.
Corpus status
documented-hoax
A documented fabrication. Peru's Public Prosecutor's forensic team
concluded the bodies are dolls assembled from genuine looted pre-Columbian
human bones plus animal bones, disguised with paper-and-rubber 'skin' and
bound with modern synthetic glue; the DNA was 100% human, and the
institutions Maussan cited disavowed his claims. The episode's significance
is not scientific but institutional: a hoax sworn before a national
legislature, the culmination of a serial promoter's pattern, and a clear
instance of spectacle damaging the credibility of the serious UAP field.
