Well, I only wanted a simple answer actually. It originated in England - therefore, the "English" (country) version of English (language) is correct.
To Assume that a language stops evolving or forking just because we call it "modern" is to err. Languages are still changing, forking, and evolving, just as they did for the last hundreds of years; evidently, several "forks" have occured in the english language relatively recently; We still have the "standard" english, but there are also forks of American and Canadian, Canadian keeping most of the idiosyncrasies of the Queen's English, such as using ou where the american dialect has replaced it with simply an o.
Now, this brings up an interesting point: how does one judge the "correctness" of a language? Within it's local context, of course. you don't try to reaad french words and interpret french grammar as english; in the same way, one has to realize that while they are still very similar, the "Queen's English" is no longer a standard by which to judge English as it is used elsewhere; And while proponents of the "correctness" of Englands English like to point out that it's called, well, "english" after england, they seem to forget that even that is really not quite true; as Computerruler has outlined, there were a number of outside influences that led to the development of that form of english, and, as I stated, languages are always in a state of constant flux and forking. ANyway, my point is, English as it is used in England is no more "correct" then English as used in America or Canada; because, they are simply different languages. Sure, English itself is a root language that bred American and Canadian English dialects, but local societal conditions and events have served to change the language in the meantime.
English itself is a Germanic Language, does this mean that the "correct" language is really "Proto Germanic"? Heavens no; it is merely a step on the path to what we have now.
A tree trunk is no more correct then a tree branch.
Anyway, I thought this was an interesting point: sometimes we forget that history is not "finished" yet.
