That’s a good question.
I don’t know that I’ve seen stats on it.
However,
OVER 80% OF THE NATIONAL GENERAL POPULATION of the USA believes that UFO’s are real and that the government is lying about them.
And, the best quality research on probabilities on such indicate that there may well be well over 3 MILLION abductees . . . and counting.
Even my relative has an implant in his earlobe that moved under it’s own locomotion (a common phenomenon that shocks medical personnel uninitiated in such things] when the Doc tried to remove it. He suspects it was inserted when he worked around such things.
Over three million you say. Huh. Wonder who's hoarding them?
Where would find the best quality research that indicates that three million have been abducted?
