I’d think a very old and advanced Alien civilization might find the emergence of a new technological civilization on another planet very interesting and worth observing. A good analogy would be a team of anthropologists observing a very primitive tribe who has never come in contact with technological civilization. As much we consider ourselves “advanced”, we may still be laughably primitive compared to them. They may even seed our world with their (very) obsolete technology just as an experiment to see what we do with it.
So my guess is that we are of academic interest to them, as long as we stay below the stage that they consider to be “threating”. Which may be a good thing as who knows what they we do if we ever became a genuine “threat”.
Earth itself would be interesting because of its congenial habitat and abundance of life. A sufficiently advanced civilization would be able to identify Earth as worth visiting through telescopic observation. A stable orbit in the habitable zone around a middle aged sun, a mix of land and sea, an oxygen rich atmosphere, and chlorophyll in the reflected light spectrum make our home planet stand out like a brightly lit rest area on a dark and dismal rural stretch of Interstate.
This would especially true if they observed us to be violent, possess nuclear weapons, and now entering space.
