The Milky Way could be teeming with interstellar alien civilizations — we just don't know about it because they haven't paid us a visit in 10 million years.
A study published last month in The Astronomical Journal[$] posits that intelligent extraterrestrial life could be taking its time to explore the galaxy, harnessing star systems' movement to make star-hopping easier.
The work is a new response to a question known as the Fermi paradox, which asks why we haven't detected signs of extraterrestrial intelligence.

Sorry, but we don't have evidence sufficient to show that aliens have never been here. In fact, it's hard to guess what evidence *could* show that. What's true is that we also have no indication that they *HAVE* ever been here.
OTOH, what would we expect to find. Suppose some alien trophy hunters landed during the time of the dinosaurs, and shot one of everything that was impressive to take their heads back. AND suppose that they were very sloppy campers, and didn't worry about garbage disposal. What evidence would you expect to be able to find, even if that area never ended up under a glacier?
I think that question just has to be filed under the "unresolved, no evidence either found or expected" file.
