So lots of people saw strange lights? All it proves is that lots of people saw strange lights.
Strange lights =/= Aliens.
This is the fundamental flaw in thinking among UFO nuts. Somebody saw something in the sky that they didn't understand. Nobody can explain it (usually because there's just not enough information available to explain it). Therefore: Aliens. Most of these people have an overwhelming need to believe in extraterrestrial visitation, so their default explanation for anything without any other obvious explanation is aliens.
While I don't think it's completely outside the realm of the possible that intelligent extraterrestrial beings could visit the earth, absent strong evidence that this has actually happened it's going to be near the bottom of my list of possible explanations for anything seen in the sky. I'm perfectly happy with, "Well, I'm not really sure exactly what that strange light in the sky was".
