It is well known that Earth consists of seven continents and four oceans, each continent boasting considerable resources and land area, while each ocean possesses immense marine resources and islands.
Since the Age of Great Navigation to present day, the European powers have extensively developed regions around the world, having colonized many small islands in the vast Pacific Ocean. It is not an exaggeration to say that European colonists can be found everywhere in the world.
However, things are not so absolute. Of the seven continents, Europe is the native land, home to numerous powers, which naturally goes without saying.
Africa and Asia are populated by numerous indigenous peoples, and with the frequent visits from colonists, the degree of development is already quite advanced.
The Americas and Australia are basically the same, first colonized by settlers and then becoming one or several independent countries, typical examples of colonies transformed into nations.
