"Why is an unidentified flashing light in the sky immediately associated with aliens?
It could be god for all we know."
"Aliens with bright lights??? At least Illegal aliens have the common sense to turn their lights off so not to be seen."
Exactly my thoughts too!!

If they do exist, to begin with, and are merely observing what we do they do it quite badly. If the light is, say, some kind of by product of their high speed travel in atmosphere or other byproduct of propulsion system why don't they cool off or whatever in desolate areas and then move on to observe the habited areas if that's what they are supposedly "stealthily" doing.
UFOs with headlights on because otherwise they would not see where they are going...

If there are aliens around I give a rat'sass as long as they have no effect on my everyday life.
