> I'll point out that if you can't hear by ~11 years old, you won't be able to understand language I don't know the specifics of this claim, so I won't talk about the argument that I assume you're trying to make. However, the argument you're actually making here is completely untrue. Almost all deaf people understand and can communicate through language. In fact, if you put a group of deaf people together for long enough, they may well spontaneously generate a language. Sign languages are real languages with almost all of the features of spoken languages (and with additional features of their own). The idea that someone can only understand "language" if they are and to hear is completely wrong. I assume what you're trying to say is that if you can't hear by this age, you will not be able to decipher sounds into language - I have no idea if this is the case. But this is an important semantic distinction (understanding language versus understanding language from sounds alone), and the fact that you seem to have inadvertently confused them seems relevant to the issue at hand: it is very easy for us to accept spoken language as a universal standard, when in practice, spoken language is just one (more common) variant of many different forms of language.
