I wrote a piece for the Open University Religious Studies blog on the 70th anniversary of the first Flying Saucer sighting, and the relevance for thinking about religions. You can read it here.
The historian rarely gets to see a narrative of this type as it develops. Compared to the origin stories of Christianity or Islam or almost any other religion, the UFO narrative is well documented and its development can be charted quite clearly. Yet there may be illuminating parallels: 70 years after Jesus’ death, Matthew and Luke were just written, new elaborations on claims of inexplicable sightings, now a generation removed from eyewitnesses.
