The alien invasion TRUMP card goes back further than Greer, Werner VB made a deathbed confession about this and more, "we had help from our friends *points upward".
General thoughts:
Remember when Q said that facts matter? What I can say for sure is that the "v2k" stuff mentioned by OP absolutely exists based on my own observations, also the reverse of "v2k" tech. Sometimes you will notice it right away if and when it hits.
I also think that some of you have a hard time thinking fourth dimensionally, once you have time travel tech, going thousands of years forward or backward is like walking down the street. Stop thinking of the distant past and future as being "distant", it is as close to "now time" as walking a few doors down in an apartment complex.
Be it ETI, ET AI, humans (of the past, present, or future), human made AI, or whatever entity is pulling the strings. If they are doing it in pursuit of scientific research purposes like OP suggests remains unseen to me, but someone or something has access to high level technology, that much is clear.
I have seen items sitting in their lowest energy state be manipulated, for e.g. a TV remote sitting on the table suddenly and audibly move, as though it had been balancing on it's edge and then tipped over to its flat bottom, yet it was already sitting flat.
Discernment frens, facts matter.
