Well, perhaps, though I doubt Sun-tzu had aliens in mind.
But given how much advanced over us they'd have to be to get here, you'd think they'd take one look and relax for a thousand years or so.
I saw a politically incorrect definition of impertinence a few years ago .... a mouse climbing up an elephant's leg with intent to rape. Us challenging, any time soon, a race advanced enough to get here would seem to fall into the same category. I suspect if we took our toys to their party, we'd rapidly find ourselves kids at a very adult party, wondering what the bleep happened to us.
If they exist at all, of course.
