I think you have - reasonably - backed down. You first claimed it was all conspiracy. Then you hedged with hoaxes and USAF testing. Then you said it was impossible for the USAF to keep such a secret. Now you're back to 100% conspiracy.
Personally, I do not think it's one thing. I agree that 90% of reported sightings have prosaic explanations of all sorts, from hoax to birds to the planet Venus, and everything in between. These are not what I'm referring to. I'm referring to the 5% or 10% that remain unexplained even after intensive investigation. The Nimitz, Tic-Tac and Gimbal sightings are examples that the US Navy says are real unknowns. Commander Fravor and other pilots interviewed seem very credible. What they report, and what the reporters report, is that they are dealing with very highly advanced technology.
Of the credible, unsolved sightings, I do not believe it is necessarily one thing or entity, nor do I believe it is strictly technology, as I have long held that unknown natural processes akin to ball lighting and other electromagnetic effects could play a role. Reference the scientifically studied Hessdalen sightings in Norway.
I seek answers because long ago I have personally experienced the phenomena in an up-close way, and have made it a life-long hobby (among many) to find the answers. I think the phenomena is culturally interesting, even significant. I think human consciousness plays a strong role in the experience of the phenomena. I think there is intelligence involved in the phenomena, but I think that intelligence could be human, even if only reflectively. See Carl Jung's writing on archetypes.
Finally, in common with the world's most famous ufologist Jacques Vallee, I think extraterrestrial biological entities (aliens) are the least likely solution to the UAP/UFO phenomena.
