I have several questions about continents:
1. Europe, Asia and Africa were European concepts before the discovery of the Americas. Did anyone else (Indians, North Africans, Persians etc) have concepts of 'continents' before adopting the European concept?
2. How would it be possible to have India and East Asia be considered as separate continents from West Asia, the historical definition of Asia to Europeans?
3. Australia was originally thought to be part of Asia by Europeans. How can this misconception be kept in existence?
