I'll start listening to UFO siteings when we figure out how to break the speed of light.
You could have a race a million years older than us who have more or less figured out how to live forever. What do you do? Maybe you build big motherships and just take forever to fly around the galaxy to look at stuff because that's all that's left to discover. Maybe they "sleep" until they get to the next star and then wake up and check things out.
Or you could have races from nearby stars who have natural lifespans of thousands of years. Maybe a 100 year roundtrip from their planet to earth is trivial.
