This episode investigates whether the Dogon people of Mali, studied by French anthropologist Marcel Griaule in 1931, possessed astronomical knowledge that could only have come from extraterrestrial visitors. Ancient astronaut theorists point to the Dogon's detailed understanding of Sirius B—a white dwarf companion star invisible to the naked eye and unknown to Western science until 1862—as evidence that amphibious beings called the Nommo arrived from that star system in antiquity. The episode expands this theory by proposing a global linguistic pattern: the syllable "do" or "dag" appears in the Dogon's Nommo, Japan's mysterious dogu figurines (which some say resemble spacesuits), and the Irish deity Dagda, said to reside in the Newgrange passage tomb. Theorists argue these phonetic similarities, combined with widespread myths of fish-like gods who brought civilization, suggest a single extraterrestrial source culture visited ancient peoples worldwide.
Mainstream anthropologists have long disputed the Dogon-Sirius connection, noting that Griaule's accounts were published decades after Western astronomers discovered Sirius B, leaving ample opportunity for cultural contamination. Skeptics also point out that linguistic coincidences across unrelated language families are statistically inevitable and that amphibious deity myths likely stem from the universal human dependence on water and fish. Still, the episode raises genuinely intriguing questions about why so many cultures revered Sirius specifically and developed similar cosmological narratives, making it compelling viewing for anyone interested in comparative mythology—even if the answers lie in shared human psychology rather than alien contact.

Theorists argue the Nomoli figurines, some found buried as deep as 150 feet and containing an anomalous chromium sphere, are evidence of an extraterrestrial visitation potentially 17,000 years ago, far predating known civilization. Mainstream archaeologists date the statues to approximately 500 years ago, consistent with early European contact with the peoples of Sierra Leone.

Theorists brought sky stones found alongside Nomoli statues in Sierra Leone to geologist Dr. Peter Ward for analysis, hoping to confirm an extraterrestrial origin; results showed anomalously high nitrogen concentrations and an apparent organic component that no laboratory has been able to explain. Dr. Ward acknowledged the results were unusual and warranted further study but stopped short of confirming an extraterrestrial origin.
