Just wanted to point out that English wouldn't still be called English. More likely it would have its own name for each race using it or it is also commonly referred to as simply "Basic."For the forces of Chaos it is called low Gothic

The inhabitants of Lakfakalle refer to English as "Ancient Aif", but speak Federation Interstellar, which they call "Lakfakalle Standard".

The Equestrians likely call it English because of the ancient humans calling it that. Or maybe because we don't like the idea of the language we speak falling int obscurity, as if the sands of time simply buried it in a vast dune of other languages. Can we not stand the thought of the very way we communicate becoming nothing more than a footnote in the great book of history, underneath the page for another language we do not speak? Is this an indication of some deeper human desire to not be forgotten? Perhaps we feel that if a part of our culture dies, we die with it. Do we even care about the culture as a whole? Or do we only care about ourselves, a survival instinct that is now outdated in today's society?

Yeah, no. It's vastly more likely that it's simply convenient to have a character that uses the same name for something we do.
