Ancient Aliens and the Extraterrestrial Extermination of Dinosaurs

RecordOBS-0646
CategoryExtraterrestrial/Ancient Aliens
StatusDEBUNKED
SummaryThe History Channel series 'Ancient Aliens' aired an episode claiming that extraterrestrial beings exterminated dinosaurs to make way for humanity. Proponents assert that human footprints have been found alongside dinosaur tracks, suggesting coexistence. These claims are presented without credible evidence and are contradicted by paleontological findings.
OriginThe episode 'Aliens and Dinosaurs' from the fourth season of 'Ancient Aliens', which aired in 2012 on the History Channel.
Claimed
  • Aliens deliberately exterminated dinosaurs to allow humans to become the dominant species.
  • Human footprints have been found alongside dinosaur footprints, indicating humans and dinosaurs coexisted.
  • Paleontologist Roland T. Bird found human tracks associated with dinosaur trackways in Glen Rose, Texas.
Evidence / consensusPaleontologists and geologists have found no evidence of human footprints alongside dinosaur tracks. The alleged human tracks at Glen Rose are known to be hoaxes carved by locals. The extinction of non-avian dinosaurs is well-explained by the asteroid impact at the end of the Cretaceous period.
> OBSERVER NOTE:
The episode is a textbook example of the Gish gallop, overwhelming viewers with rapid-fire unsupported assertions. The human-dinosaur track claim is a recycled creationist trope, long debunked by actual fossil evidence.
