Because most of them are still being colonies of Great Britain (the named parliamentary democracy).

Presidential Democracy (people vote for president) and Parliamentary democracy (people vote for poltical party and party leaders vote for Gov. head leader/prime minster)

I do not understand this question: South America is already a continent, and at the moment, all countries are democratically governed.
Democracy in America was created in 1835.
The governments of America and Britain can be compared because they are both democratic countries that have a system of separation of powers, with an executive branch, a legislative branch, and a judicial branch. Additionally, both countries have a strong emphasis on individual liberties and rule of law. However, there are also important differences, such as the parliamentary system in Britain vs. the presidential system in America.
Democracy is very rare on the continents of Africa and Asia (between these continents, you have over 100 countries and roughly a dozen are democracies). Democracy is present in Latin America in name, but in many cases, there is an extraordinary level of corruption, which derails the democracy. Democracy is only really present in Europe, North America, and Australia/Oceania.
