Yes, I'm certain you do!
I was comparing: don't move even if your
hair catches on fire, to the same device used in: if I were to speak every known human language and even the language that
angels speak.
That isn't to say the angels don't speak some language that isn't of earth, they very well could. But neither is it to say that paul was declaring that angels speak some special language and humans can speak that very language they speak.
So if I were to insist that I know for a fact that angels don't speak some language humans don't speak, I would be wrong because I can't know that. Conversely, if I were to say angels do speak some language humans don't speak but that believers can speak that language, I would also be wrong, because I can't know that.
