Well, as an “ancient astronaut theorist” fan, I take exception.
The History channel’s Ancient Aliens program loves to invoke variations of the following:
“As Ancient Alien theorists believe…” as if all of us who accept that aliens from literal eons ago planted us here, or, messed with us, or, … well, there are endless possibilities. The point is, yes, aliens, as well as ultra-terrestrials and — who knows what all non-human else — had their way with us. This belief does not mean that I accept every answer/theory/opinion/belief put forth by the pundits on Ancient Aliens.
Some of those pundits are thoughtful, and simply offering up ideas and speculations. Others are intoning theories as facts. And, one of my personal pet peeves in all aspects of my life — regardless of the hat I may be wearing at the time — being included in something I had no say in. As in, for example, work. “Well, we agree that staff should, from now on…” Excuse me, “we?” I don’t recall being asked, and I certainly don’t fucking agree. Passive aggressive manipulative tactic, that.
So, while I do believe the aliens have been around, and in fact, responsible, for the us that is now us, I also don’t believe every damn theory that comes along. And while aliens, as in from outer space, literal ETs, there are also entities about and afoot that are from right here. Within earth, parallel to us, co-existing in some sort of near-by dimension, and outer space has nothing to do with it. The two (or three or eleventh-hundred) exist at the same time, all playing their particular game.
