They also happen to only visit Amerika too. Aliens, for all I care, is a purely epistemological uncertainty. I stay agnostic on whether or not they are out there. What is absurd is that while all these devices we have pointing up at the sky to see and hear things from all the spectrums detected no UFOs, yet the aliens are just there hovering above Amerika. I would expect extraterrestrial life studies to come from some meticulously put-together study from scientists (who are very good at pattern recognition and also statistical reasoning). The simplest explanation here is that they're just a distraction deployed en-masse.
