Relax.......
You mentioned that it’s “possible”, hence my response.
It all goes to the larger picture of looking for the most likely, rational and scientifically provable theories when applying it to anything, like politics, murders, UFO abductions, etc.
I just solved the abduction “mystery” for you, so you can take it down from “possible” to out and out moonbattery. ; ) With the caveat that anything is “possible”.
When there is hard evidence of Aliens visiting our planet or a conspiracy to kill JFK, I will believe it. Until then, no dice.
