Because I "believe"--or, more accurately, guess, based on known evidence--that the odds of intelligent life as we define it presently existing in the universe are approximately 1/[the number of planets estimated to exist in the universe] (mainly because the cosmic "weather" is not (yet) working in lasting complexity's favor), I'd have answered "no" on the poll.
I wouldn't be surprised at all if humanity was the universe's first "intelligent" species. Or second. Or only, ever, forever. We know space is a fucked up, dangerous, inhospitable hellhole. The PBS image of a galactic Manhattan swarming silently and invisibly all around us seems like the religious irrationality to me.
I know one guy in Israel who thinks the same thing for the same reasons (except he's a cosmologist, so he can explain it better). Also--huge fundie. Just goes to show ya.
