I agree with T0J0, with the mega zillions of stars out there, the chances of this system being the only one supporting life has to be pretty low. I'm sure that there are species that are zooming around the cosmos at will tho. A species that is intelligent enough to span the gap of space and time wouldn't abduct Cletus from Podunk county and gang probe him. I think that there would be more abduction reports from say, scientists, leaders, artists and the like.
Also, a species that is looking for life probably wouldn't look too hard in this remote arm of our galaxy. We are way out in the middle of nowhere star density wise.
