Continuing with the numbers game and using very, very conservative estimates, if Earth were even a one-in-a-billion Goldilocks, "just-right" planet in terms of right-type sun, mass, element composition, distance from star, etc., etc., such that intelligent life and civilizations could evolve like on Earth, there would still be several thousand "Earths" out there in the Milky Way alone. A more reasonable and less conservative estimate would be "one-in-a- million", in which case the number of "Earths" could number in the millions. This also fails to take into account the very distinct possibility of interstellar migration and colonization by some civilizations much older and more advanced than ourselves, in which case the number of populated planets could easily run into the billions. I remember having these exact same arguments on Usenet 15 years ago, when the debunkers were then claiming that there was no conclusive evidence of extrasolar planets, therefore they must not exist, therefore Earth must be unique and alien spacecraft impossible. It's a really dumb argument, a classic "absence of evidence is evidence of absence" line of illogic. David Rudiak Listen to 'Strange Days...
