In aviation, "Unidentified Flying Object" is just that, something in the air they couldn't identify. It's not the same thing as Extraterrestrial Intelligent Life. Less than a year after moving to CO I saw three lights in the night sky that climbed and then faded out. My best guess is they were missiles of some sort, that headed east over the Sangre de Christos, maybe from the Pinyon Canyon maneuver site. What I think I saw was the initial exhaust plume and then a shot from behind as they moved out of visual range. Not unlike watching a shuttle launch.
The book Probability 1 talks about the Drake equation,
https://secure.wikimedia.org/wikiped...Drake_equationThe Drake equation states that:
where:
N = the number of civilizations in our galaxy with which communication might be possible; and
R* = the average rate of star formation per year in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fℓ = the fraction of the above that actually go on to develop life at some point
fi = the fraction of the above that actually go on to develop intelligent life
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time such civilizations release detectable signals into space.[3]
But as someone else mentioned earlier, there's no point in worrying about it until there is some real proof.
