Weird or What?

Ancient Mysteries (2x10)

Air date: Nov 21, 2011

Three ancient artifacts that could turn the history of the world upside down: In a Mexican cave, a young girl finds a bizarrely-shaped thousand-year-old skull that may prove aliens once walked the planet; featuring detailed images of dinosaurs, a Peruvian doctor discovers ancient stone carvings that could rewrite the story of evolution; and, excavated from one of Cairo’s oldest pyramids, a 2000-year-old wooden model may be proof that ancient Egyptians invented modern flight.
