how did our language derive from nothing?

I'm surprised no one mentioned this. Your infromation is far, far off. Chimps are apes, and chimps are much closer to Humans. The brain thing doesn't make sense. I beleive humans and chimps are 4 million years from each other, but I could be wrong (I read The Third Chimpanzee a few years back). A little while after we split one gene that controlled making the jaw bone extend turned off. This allowed our brain to grow simply, because there is more room. With a larger brain you can store more infromation, and about half our brain is for language, and that can easily evolve in four million years.

It was the turning off of a single gene. Intresting that we only have thirty thousand genes. According to Jared Daimond in the third chimpanzee we are only 4 million years off chimpanzees, the gene turning off happened after the split, because chimpanzees do not have that gene (well I should say they do have it because its us who doesn't have it).
