Btw—I can’t resist—I am going to take my best stab at my question list:
Q. How many alien races are there who have visited the planet throughout human history?
A. It depends on the definition of “visited”. We are probably talking single digits of races that have physically visited, triple digits of races that have communicated with people through dreams or telepathy or other “occult” non-physical means.
Q. How many alien races are on the planet right now?
A. At least five.
Q. What scientific principles have aliens discovered that our standard science has not recognized to date?
A. A bunch—all well beyond my technical ability to understand, much less explain.
Q. Same question for technologies?
A. Anti-gravity, nanotechnology (and even smaller scale AI), cloning, total genetic manipulation, manipulation of souls, telepathy, invisibility, fully intelligent and independent avatars, portals for travel of any distance (creating and using existing ones), mind-reading and mind manipulation, remote viewing, advanced races may be able to create new “intelligence” up to the scale of space-craft and even planets or stars.
Q. How often have the aliens interfered with human history—say in the last thousand years, hundred years?
A. Many times, sometimes on purpose, sometimes by accident.
Q. Do the aliens use some form of time travel? How does it work? What are the constraints? What about viewing the past or future? (same questions)
A. Yes. There is a lot of debate about these details. I do not know enough to have an opinion on these.
Q. How many humans have been kidnapped by aliens in the last hundred years? What criteria did the aliens use to choose their subjects? Was this done with or without the consent of any human government or authority?
A. I think we are talking at least several hundred thousand worldwide. They seem to be interested in certain types of DNA and often kidnap multiple generations of families, but I do not know the exact criteria. There are rumors of treaties with the Deep State with some whistleblower claims—but no documents have been produced.
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.
