Over one-third of the folks would greet them with hand guns and bazookas, one third would be running hysterically into the hills, north, south or wherever they could be 'safe' and the final third would be racing to ask for a homeworld tour.
Sorry, in my opinion at least two-thirds would be up there trying to sell something to the suckers...er, I mean, brothers from outer space.
