No one has provided convincing beyond a shadow of a doubt proof.

Not to you, at least.

And "proof" of what, exactly? No one seems to know what we are dealing with here.

It's something invading our airspace (in military training areas and around nuclear facilities), but a clear definition of "it" has not been presented (to my knowledge).

There is an important clue.

The flying objects are unidentified. That means that they are unknown as well.

Uncertainty is always ok except to those who insist on certainty in all things

Exactly. In the absence of fact anyone's opinion is equally valid, including those who are hard core skeptics like myself.
