Aliens are a distraction
As long as people keep going down the path of arguing for or against the "It's Aliens" belief, time and effort will be wasted that could have been better employed on the much more important point :
"Some UAP appeared to remain stationary in winds aloft, move against the wind, maneuver abruptly, or move at considerable speed, without discernible means of propulsion"
I couldn't care less where they come from - what I want to know is how they do that? That's a much more interesting, and potentially valuable, question to answer.
Scientists should be jumping all over that one.
