Mexican Congress heard from researchers Tuesday, Nov. 7, who said Peruvian mummies are real. But the researchers declined to label the mummies as extraterrestrial life forms.

Journalist and UFO enthusiast Jaime Maussan initially presented the specimens on Sept. 13 at a congressional UFO event.

During Tuesday’s session, Maussan aimed to verify the authenticity of the bodies, supported by a panel of doctors confirming their biological origins.

Maussan and his group of researchers showed photographs and x-rays of what he said was a “non-human being.”
