Come with me on a flight of fancy. What follows is pure speculation, but to the best of my knowledge does not require impossible things like warp drives.
Millions of years ago, a race of intelligent creatures developed somewhere in the universe. Either by nature or their own development they managed to get along with each other and thrived on their own planet. Then something happened that caused them to branch out into space. Maybe they detected some incipient catastrophe or maybe it was simple curiosity.
Given the limits of physics that have already been set out here, they decided to develop multi-generation spaceships. Gigantic spaceships that were totally self sufficient and contained a (relatively) large number of "people". They managed to build and send off a fair number of these and the inevitable glitches didn't destroy all of them.
Their nature enabled them to live together in these conditions without killing each other and they all agreed to limit the population, limit personal consumption and other necessary features of life in such an environment.
They didn't need to travel at very high speeds as they understood, and accepted, that their journeys would take very long stretches of time no matter what speed was involved. Over time they became totally adapted to life in their spaceships and even when some livable planets were discovered, they had no wish to live on a planet again. Over time they built more ships so their population could expand, and also to allow more exploration. Eventually huge areas of the galaxy contained at least some of these travelers.
Occasionally they would come across a planet like Earth that was populated by intelligent beings that they could potentially reveal themselves to. After much deliberation they decided that the risk of doing so was too great and they would simply observe for a while and move on. Their "observation drones" were occasionally seen by people on the planets and referred to as "UFOs".
