Who would you appoint as Earth's ambassador to alien races, and why?
Many ot the answers suggest that our knowledge of the possible alien(s) will begin at zero (and more likely at less than zero since most of us have already formed some kind of assumptions about what they will be like),. Earth's "ambassador" will have to be ready for anything.. This might require an astrophysicist, some would suggest Hawking, or (and this would be my preference) a mystic. Who among the living mystics is most open minded and open hearted and most ready to die for the rest of us? We would have to search for her (or him or it) among our hidden treasures like searching for the Holy Grail. Any body famous (like the Dalhai Lama) will probably carry too much baggage. Because true mindfulness will look so much like total mindlessness, we will probably overlook the best candidates completely. Maybe we will just have to take our chanches like the Aboriginal peoples did with the Europeans and hope that these aliens are far more transformed than we are.
