As in his "Chariots of the Gods" …, Däniken once more strains scientific credulity [in "Gods From Outer Space"], but intrigues and fascinates with his bold theories and speculations about mysterious "visitors" from outer space in ancient and prehistoric times…. His interpretations of the old myths and writings are less provocative and exciting than certain of the tangible evidences he discusses, such as possible ancient "airports" in Peru and Chile and artifacts found around the world which science has never explained. Däniken may be a "Sunday archaeologist" but such open-ended possibilities as he proposes make for absorbing reading and appeal to the eternally curious amateur in each of us.
