Those that have never witnesed a UFO will never believe it until they have actually seen one. As a youngster growing up on the farm, with no AC, a lot of time was spent outdoors even in the evening. Not counting the hundreds of times camped out sleeping under the stars or varmint hunting or fishing at night. I have seen many unexplainable phenomina yet to try and explain that to someone who has never spent much time outside at night is near impossible, they just refuse to believe it.
There is much truth in your observation.
