Egypt, temple of Sethy 1 in Abydos, strange carved hieroglyphs, called "Abydos helicopter", sometimes seen as a proof that aliens met Ancient Egyptians. These signs can remind an helicopter, an airplane, a char, some say a submarine. They belong in fact to an inscription showing the names of the king Sethy 1. The hieroglyphs were modified to show the name of the successor, Ramses the second, some of the updates in plaster later falled. It's a "palimpsest".
