ordinaryguy - I agree about the human hubris. I also find it impossible to believe we're alone, tho I have no illusions that other intel life will look anything like us.
There's a new Seti project I saw on last night's NovaNOW. They're setting up hundreds of radio telescopes that will eventually have the equiv of one > couple hundred of feet across (or was it miles?). (I didn't read the whole Post article, so sorry if this is old news).
In case you didn't know, you can help. Seti@Home uses volunteer computers to help them crunch the data. Check it out (I'm gonna sign up as soon as I get a better 'puter):
