And you're certain of this, how?
The evidence is already extraordinary. Many eyewitnesses, sensor and camera data all simultaneously recording encounters over a period of years. The footage that's been declassified is merely the tip of the iceberg of what the military has available. I would imagine we're talking about hours upon hours of footage and hundreds of eyewitnesses who are remaining quiet due to fear of ridicule or reprimand.
We send these craft to harass our own troops repeatedly... potentially causing them to open fire and destroy them? Are you serious???
Stealth fighters were tested out in Area 51 because it's sparsely populated and those who did so knew exactly what they were doing. They did not fly the U2 or SR-71 in such a way that they would get shot down by our own troops. You citing friendly-fire is bogus. That's about a hot war zone, not routine peacetime maneuvers.
I'm afraid, as the Bard once wrote, "There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy."
As I've made my rounds online on this topic I encounter types such as you, those for whom no amount of evidence will ever be sufficient. It will be interesting to see how large a segment of the population that turns out to be. Considering that 40% of Republicans don't even think the election was legit it's easy to see how people have severe critical thinking deficits. Look, I'm not denying it's a tough leap to accept the presence of aliens. I used to be a skeptic but the Nimitz footage released in 2017 through the New York Times broke through my resistance. If the evidence manifests itself, at some point you have to just defer to it, as fantastical as it may be. It's like, we routinely watch sci-fi where we go out and meet aliens all the time but we have this mental block that prevents us from considering the idea they're coming here? I just don't get it. I mean, I know the field is full of quacks and grifters, and many of the specific claims they make are highly speculative and probably bogus, but that doesn't necessarily mean there isn't some truth underneath it all.
