The British didn't create the language, I have no idea who taught any of you that, or why...
The English language was not created by a single country or group of people, it was used all over in order to be able to understand one another way long ago. It's basically the universal language, and this whole debate should solely be based off of personal preference, and not factual evidence, as it would contradict itself. ._.
American English is a shitty language, It's a pidgin compared to the awesomeness of English spoken in England from about 1600- 1900. Modern English in general is completely ****ed. BTW, this is coming from a proud American :-)
