Don't get me wrong, I'd like to think there is extra-terrestrial life. I've seen strange lights in the sky that don't tend to have any concrete answers associated with them.
I don't think the two are connected.
Even if we work with the Drake Equation ( http://en.wikipedia.org/wiki/Drake_equat
We have to make a couple more huge assumptions.
1) That on the cosmic dartboard, their dart of "Hey lets go check here" lands on a fairly uninteresting arm of a minor spiral galaxy.
2) Even if the dart did land here, that they'd be interested.
I tend to look at UFO enthusiasts these days like I look at the truly religious: Its a neat idea. If it helps you to sleep at night, great. But their belief is utterly personal, and utterly unproveable to anyone else but them. What works for them does not work for me.
Not to mention the question of: "If there IS intelligent life out there, why is it so bloody interested in our redneck population?" ;)
