There are loads of books on this subject - just head off to the local second-hand bookshop and have a look in the Esoteric section. Plenty of nonsense published in the late sixties-early seventies by Eric Von Daniken, Charles Berlitz etc., about aliens, technology, archaeology, and ancient civilizations. Some are very funny. Most of them appear to spring from Cold War social uncertainties and anxieties at the time, combined with the excitement caused by the USA/USSR space programmes and the Moon landings.
