I heard of a theory once which stated that extra terestrial UFOs were not likely to appear more than once every 10,000 years or so, based on number of interstellar capable civilizations, number of stars they would have to visit to stumble over us, number of surveys they did each year etc etc. Can someone give a more detailed reference to this theory. Also, In determining the probability of intelligent life on other planets, On what statistical sample do people base their arguments. Seems to me we have a sample of 1 (earth) and this makes it invalid to talk of the probability of a planet having life as 1 in a billion, or 1 in a billion billion. Comments please !
