Greenland ...why the name???? The maps like Piri Reis described the earth as it was without ice.... whether those changes happened thousands of years ago or millions of years ago maybe speculation, but the map is real and depicts centuries ago what we came to discover by means of technology in 20th Century. Or the poles shall move or orange crust layer of the earth and then Peruvian and Brazilian Amazon jungle could freeze their beasts and vegetation while Russian frozen areas will become tropical areas and scientists of the future will ask stupid questions like "how come the Japanese metal snake (bullet train) traveled? Or what was the purpose of those rectangular devices broken in pieces with the inscription saying "Samsung"...
