Earth has been around for about 4.5 billion years, about 1/3rd of the age of the universe. If another technological civilization that is more advanced than us by even 1M years is watching earth, and suddenly this planet starts spitting up rockets, satellites, nuclear explosions etc., that seems pretty interesting. That's one species out of 2+ million on earth, which is one of trillions & trillions of dead planets, that manages to transcend the atmosphere.
But to your point, I guess at the scale of even just the known universe it's hard to assert that anything is common or rare.
