I assume you mean UFOs as in "alien flying saucers".
I think the rationally correct belief is that we simply have no evidence of aliens at this time, and since we virtually know absolutely nothing about what pilots saw (all we know is that there are these observations), we just fall back to our priors (base assumptions). Sure, it might be aliens. And hence the ancient aliens meme. It might all be secret military stuff. (Or the mix of the two, hence the storm Area 51 meme.)
And in this case I don't see what's wrong with the standard narrative.
If there are truly aliens flying regularly in our atmosphere we should strap a few 4K recorders on regular airline planes, and we just have to wait.
Not to mention the increasing number of space launches and spacecraft up there. And increasing number of downward looking observatories.
