What did Garry say that you found particularly intriguing?
There is a history for this stuff that goes all the way back to the beginning of civilization.
Abraham’s family came from UR at the time that the Sumerian civilization was cracking up and going down. They were basically refugees. The Sumerians were as to the 2nd millenium bc middle eastern empires like the babylonians as the greeks were to the romans.
Sumerian myths make it look like space aliens came to earth.
In 2016 Elon Musk was interviewed in one of the Persian Gulf cities for arab television. the interviewer preambled his question about UFO’s with the observation that in his part of the world it is believed that Adam and Eve were space aliens.
We have the genetics to show that human evolution is much slower than a mere 6000 years which is the length of the jewish calendar which dates to the beginning of the sumerian civilization.
So something else —besides just space aliens landing—is going on.
Some people have suggested that what is going on is so profound that if humans knew the half of it, we would run the risk of having our very personalities destroyed/erased.
This is what happens when we learn that reality itself is not even remotely what we thought it was.
This line of thinking basically suggests that our very personalities are constructed on our perceptions of reality and do not--cannot--exist in without them (i.e., in a vacuum).
Students of the Bible will see a parallel in Luke 21:26: "Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken."
