How did Europe become separate?

Well, Europe isn't a country, it is a continent. You don't say in the US, that you and Canadians and Mexicans are all the same. That's an insult! Same goes for Europe; don't call a Englishman or a Dutchman he is a ''European''; he'll be angry with you! Also, you acnnot say; Brussel is the capital of Europe; it is the capital of Belgium. And Paris doesn't lay it Europe, but in France!
