It doesn't matter if they called them “UFO’s” or “dancing disco lights” or “weird lights in the sky”.
The simple fact is that the modern “UFO sighting” is based upon a modern mindset of extra-terrestrial life and technological means of motility.
There is simply nothing previous to humanity knowing of this possibility that compares in essential details.
If there was an ancient scroll talking about such a sighting, with a picture of a “gray” as described by many in the modern age, and a drawing of a lighted up disco disk; I would concede that there may well be such things visiting us, and that they probably have for a long time.
But that is simply not the case.
In the mystical age the sightings of the unknown being from elsewhere was mystical.
In the technological age the sightings of the unknown being from elsewhere is technological.
Why the change?
What makes you think any Government Agency would reveal contact they might of had with Alien Technology???
Would that not be a Security Risk?????
A bit more here...
The first objective in the military recovery of foreign vehicles is to examine the vehicle for new and advanced technology with a view toward reproducing that technology through devising methods of fabrication and manufacturing.
If this technology comes from another off-world culture, the objective has an even higher priority as such a culture has demonstrated a feat beyond the capability of our own technology. The military thinking on this is to treat such incursions by alien technology as possibly hostile and a threat to our national and global security.
We must act to even the odds as soon as possible to develop counter-measures to a possible military threat to our systems of defense. This is why reverse engineering becomes imperative.
Some of the systems that would be studied include:
• The energy or fuel the spacecraft uses for power
• The propulsion system
• The navigation system
• The information system(s)
• The life-support systems
• The communication systems
• The weapon systems
In addition to these systems, the actual material structure of the spacecraft would be studied. If the aliens were found wearing flight suits, a study would be made of the material and methods of fabrication. If the spacecraft were able to defend itself through high-speed aerobatic maneuvering or using defensive shields or counter-measures, an assessment of these capabilities would be of prime importance. The study would have to eventually extend into other scientific fields to obtain a broader picture of the alien’s origin and mission, which would include autopsies of alien bodies and a profiling of the alien psychology and motivation. In fact, every clever way that you could think of would be used to study the alien and the technology. And all of this would have to be conducted in utmost secrecy so as to maintain a decided advantage in the scheme of things in the global political arena.
Let me ask a question:
Do you mean to say UFO sightings are non-real events, or that merely the names given the events differ based on the level of technology (or culture) that existed during the event?
