We atheists criticize the "God of the gaps" fallacy of some theist arguments. "Ancient Aliens" is built upon the "aliens of the gaps" fallacy. The theists say, "I don't understand this -- therefore, God must have done it." Giorgio Tsoukalos says, "I don't understand this -- therefore, aliens must have done it."
No. He doesn't understand this, and that, and that, either because he's an idiot, or because he's pretending to be -- which pretty much amounts to the same thing.
I really, really hate the show. I know that very many of you love it without taking it seriously, but I wonder if you realize how much more interesting and exciting TV shows on pyramids and angels could be if the very best scholars were allowed to assume the roles of Tsoukalos and his nimwit colleagues, and tell you what we actually know. Imagine: all those beautiful pictures that you see on "Ancient Aliens," but instead of them being accompanied by nonsense, what if you could actually learn something about them and the people who made them?
It can be done. All you need to do is drop "Ancient Aliens" and all the other crap from the so-called "History Channels," and turn instead to some real historians, and real archaeologists, and so forth.
The "History Channels" are right-wing operations who want to keep people stupid and voting Republican.
Donald Redford, for example, is a real archaeologist, who wants to lay some real knowledge on you.
Ain't nothin' like the real thing, Baby.
