I meant we send drones to crawl un mars because it would be very inconvenient to fly there for the human body.
Same with a more advanced race curious of the deep space.
All life must eat and shit and sleep, where ever in the universe.
So sending drones to earth to inspect us is as logical as us sending the Mars rovers.
