He also said that there are two sorts of ufos........the ones we build.......and the ones 'they' build!
Surely the UFOs have to be the ones WE build?
These objects cannot possibly come from Outer Space, or if they do then they must all come from the same place because descriptions of them rarely vary (with exceptions such as the Phoenix Lights) - which is why they've been called 'flying saucers'.
But given that it's known that no planet in our universe has any sustainable form of life let alone one that could possess the knowledge necessary to build such superior technology, it would have to be supposed that they came from much further afield, and that just has to be nonsense. For example, the distance from the Earth to the edge of the visible universe is 46.5 light years. The 'aliens' flying these craft would never survive the journey!
Look, there are plenty of extremely large, uninhabited areas of this planet, so my guess is that some persons have been, and still are, playing silly buggers in one or more of these desolate locations, building these objects, possibly underground, and conning those who wish to believe (I won't insult you by calling you gullible) that Earth is being visited by so-called alien craft from Outer Space.
