Weather
Weather ballons my ass. Man any that intelligent. Just a little over 100 years ago there was only the horse and buggy 20 years laterthere wers factories and man just learned to fly. You dont go from lift and thrust tojdt propulsion to antigravity technology in so short a tike spend given the fact that the greatest minds on our olanet Einstein, tesla etc couldn't even recreate that technology. If we did make thise ships is because that technology was reverse engineered from thise crash ships and they are also getting help from alien beings. Some of the tech we have now is reverse engineered alien tech.
I like your thoughts and your reasoning, however, I still err on the side of man made vehicles and US mand made vehicles. 1) the aircraft highlighted for the video are ones that have been declassified and they are used as the weather balloons in the infamous Project BlueBook report - all UFOs are weather balloons.
My thoughts are that these vehicles are so classified that its propulsion systems and other aspects are so advanced they may not even be in military budgets or part of the military - however because they are US-made vehicles - they do not set off a panic amongst the leadership because they know otherwise - we would always be on mass alert because you have foreign vehicles flying over the US - with unknown intentions - with the ability to drop bombs anywhere - yet you do not seem to see that level of concern - because they know what they are and the intentions - they are US.
Now if I am wrong on the front, my alternative is not aliens from another galaxy ( and yes they do exist but distance is a bitch) but beings from another dimension, and as this video explain how it is possible and more plausible than it might seem ) higher dimensional beings can transition more easily to lower dimension than vice versa.
