Most UAPs are piloted by humans - some are piloted by members of a parallel civilisation

The 4chan "leaker" described a mothership which manufactures the UAPs and maybe the greys too under the sea.

Perhaps, a long time ago, there was an actual ET spacecraft traveling the long distances (maybe with warp drive or somethign) in a pre-modern era and deposited the autonomous factory/underseas ship.

That ET spacecraft would presumably be large and obvious to us now with technology, but back then, it would not have been observed if it came in over deep ocean.

The recovered UAP craft and drones may not give us the technology for interstellar flight. That may still be yet another generation or many more beyond.
