The starting point is that I apply logic, reason, understanding of history and technology.
Why would such an advanced civilization allow themselves and it's technology to be captured?
I don't believe anyone has claimed they have "allowed themselves and tech to be captured." Logically, they are subjected to the same forces of random events and technology failures and user error all forces of nature are subjected to. It's hardly 'far fetched' to believe space crafts might have mechanical, technological, or user failures. Or be shot down. Not understanding how this is a hard concept.
Also, your position is internally inconsistent. If it's such secretive advanced tech, why are we flying it around in rural or heavily populated areas where people will see it? Would that not give the other side great opportunity to copy it, or opportunity for it to crash? It makes no sense to have this secret tech and fly it around over Topeka or Phoenix or in other nations like Mexico, etc. These sightings occur over the world.
Eye witnesses are fine, but it doesn't automatically mean aliens. Statistically speaking it's a much, much higher chance they saw our own tech, not aliens.
No, no it's not. Statistically, mathmatically, historically, and technologically speaking these are more likely alien technology that has visited. Consider these observations occurred by military aircraft pilots of ALL sides of the WWII war, and labeled "foo fighters." To believe any side of the war, Allies or Axis, had such a leap of disruptive technology but did not employ it nor was it ever discovered, when the fate of the world was at stake, is nonsense. Yet here's pictures and many veterans said they saw these orbs in the sky. This predates the jet engine or rocket missiles, and our instruments were generally all analogue technology. But to believe as you suggest, someone had ORBS yet did not weaponize them in any sense? I don't believe that's even plausible.
This and similar such objects have been seen by millions of humans over decades and even centuries, far before man invented flight to be specific. Columbus documented in his journal a UFO sighting. There are religious paintings with chariots in the skies from Biblical times.
The reality is that for thousands of years, these advanced creatures have visited to study humans and earth.
Same as above, you don't know what you saw, therefore you cannot say it was alien. It is likely extremely advanced tech of our own.
False. Because applying logic, reason, history, etc. of all known tech, this tech is decades more advanced from where we are now in 2023. And I saw it decades ago. What I saw I would estimate is not even humanly possible (without alien tech to copy), for many more decades. If we've had this ultra sophisticated tech, why have we not used it for space travel, war, or other applications? Why? Why are we just sitting on it since, presumably at least the 1980s but instead keep going back to plain old rocket propelled fighter jets and bombers, flying the POTUS around in an invisible clocking device silent triangle, etc? It would be completely illogical to have this tech and not exploit and use it.
So for how long have we had this fantastic tech and not used it to any significant advantage? How do you explain all the photos and videos, the abduction evidence of which many stories are very credible, etc.?
Imagining all these fantastic things is fine, but it's still just one's imagination.
So instead, millions or maybe billions of UFO sightings going back decades, or centuries, is all just a big mass hallucination?
What is your explanation? There are a finite number of possible options.
1. US technology. This fails to answer it b/c it's been observed for decades and centuries yet we are not employing it, it befuddles are most trained fighter pilots and engineers who speak about the tech, and it's seen around the world not limited to "safe" US airspace IOW where it could be captured. To believe this, you'd have to believe we've had crazy advanced anti-gravity flying machines with cloaking abilities since, at least the middle of the 1900s. That's implausible and leaves many unanswered questions as to why we never used it in any wars or for any nobel causes...
2. Enemy technology. Similar analysis. Also there are a finite number of nations so advanced this is plausible, maybe 3 or 5. Not likely.
3. Rogue civilians? Impossible. The costs, the tech, the lack of any actions to sell the tech to anyone, etc. And it's been ongoing for many many decades across the globe.
4. Alien technology. This is what we are left with.
Do you have any better theories, if you do I'm all ears??
