No, I think you're missing the point here. Because one, that's an unevidenced hypothetical that is basically a fantasy. I am not obliged to give it any weight.

And two, if I did, it does not explain why UFOs have remained always liminal despite our rapidly advancing technology to track and record things. If shy aliens were vastly superior, we'd never detect them at all. If they were at some lower but constant level of technology, we'd detect them more over time. But for some mysterious reason, they were just as detectable in 1953 as they are in 2023. Your "aliens r smart" theory does not explain that at all, and so it's not helpful. And it's especially not helpful as a reply to my original point, which you do not yet seem to have taken on board.
