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?
Yes. That's an oversimplified way of how words work.
Words are by general consensus.
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.
You can make up any definition you want, but here is a generally accepted definition of the word 'continent':
con·ti·nent
/ˈkɒntnənt/ Show Spelled[kon-tn-uhnt] Show IPA
noun
1.
one of the main landmasses of the globe, usually reckoned as seven in number (Europe, Asia, Africa, North America, South America, Australia, and Antarctica).
2.
a comparable landmass on another planet.
3.
the mainland, as distinguished from islands or peninsulas.
4.
the Continent, the mainland of Europe, as distinguished from the British Isles.
5.
a continuous tract or extent, as of land.

News flash: Americans = all citizens born in the continent of America.
America isn't a continent.

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.
When did I ever say I was superior to anyone? When did I ask for any special treatment? There really isn't any reason to get personal.
