A British author of several books, beginning in the early 1960s, centered around a theme of visiting aliens (both ancient and modern), spaceships, interplanetary travel, and so on, using biblical references to back up these speculations. So, for example, in The Sky People (1960), he placed the Garden of Eden on another planet and identified Noahs Ark as a spaceship manned by aliens who were rescuing humans (the result of one of their biological experiments hybridizing apes) from possible extinction. Such flights of fancy were really science fiction, but, together with many similar extravaganzas by Erich Von Daniken, Immanuel Velikovsky, and others, they struck a chord in the popular imagination and were treated far more seriously than the evidence warranted.
