Abydos, 1848 – In this ancient city in Egypt, the temple of Seti I was discovered. On one of the ceilings of the temple, strange hieroglyphs were found that sparked a debate between Egyptologists. The carvings appear to depict modern vehicles resembling a helicopter, a submarine, and airplanes. At first the images circulating were thought to be fakes, but were later filmed and verified as valid images. Egyptologists have tried to offer a rational explanation.
