Q actually made two statements, and they are not necessarily connected in the way we all thought.
Pic irrelevant.
Anon asks, "Are we alone?"
Q answers, "No." … Which one might interpret as, no, we are not alone, God and His angels are with us.
Q continues: "Consider the vastness of space." … which one could interpret as suggesting that space is too vast to allow for any physical being to travel between star systems.
In a separate drop, an anon asked: "Are UFOs a distraction?" To which Q answered, "How far away is the closest star? What do you think?" Which also could be read to suggest that UFOs are indeed a distraction (i.e., they're our own classified tech) because it's impossible for physical craft to travel that far between star systems, with the nearest star (other than the Sun) being Alpha Centauri at 4.4 light years away.
All I'm saying is that this question has not been answered by Q as clearly as many of us first surmised.
