David Spergel, who is the head of a NASA panel to study UFOs, has said that he has only seen reports of two allegedly "non-human" corpses that were displayed in the Mexico Congress.
Spergel urged the Mexican government to make samples available to the world's scientific community.
In the Mexican Congress, the event to unveil the two allegedly "non-human" corpses was spearheaded by journalist and UFO researcher Jaime Maussan, who testified under oath that almost a third of their DNA is "unknown" and the specimens were not part of “our terrestrial evolution”.
