This saying is fitting to this peice of evidence that seems to suggest the phenomenon of UFO's has been around since the start of human civilization and yet it is consistently dismissed by so called experts.

Some people believe that this was just how the people of that period interpreted the things they were seeing or perhaps there is a literal connection between the spiritual and UFOs.
