As I pointed out, there's a lot of human psychology involved! Using hypnosis I can make anyone believe having experienced an abduction by aliens. Including the whole typical research they'd do on humans.
Hypnosis only works on those who are happy to be hypnotised, and even then most won't experience something strong enough, and of those who do many won't retain that belief after they leave their state of hypnosis.
While I'm happy to accept that whole paragraph was a joke (with the wink at the end), it was a funny thing to hear from someone who seems to be all about psychology.
I don't want to get into the rest of the discussion -- I don't have the time to look at conspiracy videos and read about stuff that I personally don't find interesting at all -- aliens.
