Well, I guess you should read up about the Tower of Babel if you think you'd prefer a single language. I'm not Christian but I am a Linguist! More frightening, I assure you. Anyways, I am currently writing a paper on Language Maintenance in Navajo and believe that the preservation of languages is important historically as well as culturally. Differences among people is a good thing, as it makes life more exciting. Wouldn't it suck to travel to other countries and see the exact same buildings, plants, animals, etc? Language is a spice of life, and once they're extinct it's hard to learn from their histories.
