In 1969, Norwegian anthropologist and archeologist Thor Heyerdahl tried to prove that even the primitive Egyptian boat, made of papyrus could cross the Atlantic Ocean.
Built by the peoples of Lake Chad, the first boat (Ra) left Morocco and sank after 5,000 kilometers around the West Indies.
In 1970, a second improved boat, the Ra II left Morocco and reached Barbados. This showed that Egyptians could truly cross the Atlantic.
