I suppose there could be a small possibility that 10's or even 100's of thousand of years ago some alien race set out probes to visit us but live alien beings flying them simply isn't possible.

A civilization hundreds or thousands of years more advanced than ours probably could travel light years in ways we could only dream of in sci-fi movies, even though they're still not likely to reach earth, specifically. Point being that the laws of physics that we currently understand won't likely be the laws of physics that make quick travel impossible.
We're dealing with space travel in terms of a few decades of serious attempts. That's a nano second in the history of a solar system, with literally billions of stars and planets out there.
