Just two observations:
1. If ‘they’ wanted to be hidden...they are doing a lousy job, and obviously have some ‘Brandon’ in charge of their operation.
2. On technology age, you can probably go and assume they are more than a thousand years older than our civilization today.
Naval officers whose ships have been plagued with these "things" have concluded exactly the opposite is the case.
They appear to be engaged in a kind of coming-out party.
First you would have to assume that there ARE aliens out there...
The other observations are spot on, though I would add that they are also terrible at hypnotising folks. The come from Light Years away, but, they can’t cloud minds well enough that a hypnotist can’t get hundreds of details out of abductee’s minds.
It’s like we are getting visited by the Three Stooges of the Extra-terrestrial universe.
