Logic?

Where is the logic of man made continents? So just because we say that river over there is the start of a new continent does that make it true?

Going by the true definition of the word a continent shouldn't be dictated by humans, but by facts, separating America into North and South is beyond stupid, same as Afro-Eurasia, this is a tool used to separate and segregate mankind into thinking that people that live in other "continents" are different from them.

News flash: Americans = all citizens born in the continent of America.

Also we are all citizens of this planet so the sooner you stop thinking you are superior to everyone else and deserve special threatment the better.
