Sagan comes in with a great quote -
The problem is summed up by Carl Sagan: “Every time he [von Däniken] sees something he can’t understand, he attributes it to extraterrestrial intelligence, and since he understands almost nothing, he sees evidence of extraterrestrial intelligence all over the planet” (Playboy 1974:151).
Unfortunately its true of so many people, and the information revolution we were all promised seems to have made it worse, not better.
Around a decade back, I and a bunch of colleagues explored these theories and despite knowing they were all bunkum, the sheer entertainment value they served was gold.
Think of it like Marvel universe stuff.
We'd go on long walks and let our 'what if' imagination run wild.
This also applies to certain "conspiracies."
In both cases, it's their God of the Gaps.
(Not to be confused with the Boss of the Ross. Or Hermes. Or Nike.)
Weird critique from Sagan, who wrote a bestselling novel based on the idea of contact with extraterrestrials.
