Origins of the word Amarra

It is curious to me that while reading a book recently the author talks about a language spoken by the Aymarra Indians and considered by some specialists to be the oldest language in the world. The author goes on to say that this synthetic and highly structured language meant that Aymarra could easily be transformed into a computer algorithm and used to translate one language into another. The book Fingerprints of the Gods by Graham Hancock discusses this on page 91.

I wonder if this is where our modern day Amarra got its name? Anybody know for sure?
