I can't recall who it was, but one relatively well known "expert" in this field said, "If you think you have seen a UFO up close, you were probably abducted."
I have close friends who have seen a UFO up close. I wonder about them.
If they were awake I don’t think they were abducted unless they had “missing time”.
While some aliens have the ability to play games with time and put you back exactly where and when you were pre-abduction there are a lot of stories indicating that many are either sloppy or technically incapable of making that happen.
