Is this a worldwide phenomenon?
The UFO story is a global one, but I think it has its origins in American culture. Not long ago there was a major UFO wave in Iran. Not surprisingly, all the UFO incidents happened near the country's known nuclear sites. Initially it was odd lights in the sky, then over a few days, the stories started getting more dramatic. They were describing small robots hovering in the skies. I read an interesting article recently that described the impact of the drone use over Pakistan and Afghanistan. The villagers describe the drones as being spiritual beings with a life of their own that live in bedrooms in space and come to feed on women and children. It is fascinating to watch, because I feel like I've seen it all before. It will be different for every nation, as they develop. Perhaps every nation will get the aliens it deserves.
