"UFO" does not automatically mean "alien ship" or "alien intelligence."

It doesn't *not* mean it either.

Assuming that something truly mysterious is going on - as the Pentagon seems to be saying - alien intelligence (and especially "friendly aliens") is not necessarily the explanation.

There are many good reasons to doubt that UFOs are from "elsewhere." And every reason to doubt that they are all one thing, whatever they are.

But we don't know what we don't know. All we know is that some reports are baffling.

And, for now - as for the past 74 years (or more) - that's that.
