With as much speciosity as ever, the original popularizer of the theory of prehistoric extraterrestrial visitors brings forward [in Signs of the Gods?] more "unexplained" phenomena to repeat his "gods-astronaut" proposal…. Along with typographical errors, there are quotes from encyclopedias, names of esteemed professors, and plenty of von Däniken's exclamation-pointed epigrams.
