Many ufologists, conspiracy theorists, and experts believe that the UFO phenomenon began in 1947 when a UFO crashed in Roswell, New Mexico. However, fascination for UFOs started centuries before that, according to researchers.

'The Baptism of Christ' by Aert de Gelder, 1710

Svetitskhoveli Cathedral Fresco, 17th Century

'The Crucifixion', 1350

'Ume No Chiri' Illustration, 1803

The illustration from the book called "Ume No Chiri" ("Dust of Apricot") shows a UFO. According to the account in "Ume No Chiri," a foreign ship and its crew landed on Haratono shores in 1803. Witnesses say that the ship's shell was of iron and glass. The account also adds that there were strange symbols inside the ship.

In 1941, a UFO allegedly crash landed in Cape Girardeau killing two "extraterrestrial" and injuring another. A pastor from a nearby town recounted that he was called in at 9 p.m. to pray for the victims of the crash. When he arrived at the site, he saw a disc-shaped aircraft, but what caught his attention were the strange symbols written inside the craft.

While the 1803 "Ume No Chiri" illustration is deemed as fictional, ufologists believe that the account is important to show that UFOs have been visiting earth for centuries.
