I mean, yeah. If someone had the technology to not only fly half a billion light years to get to our little mud ball (in person or with advanced machines) they’d have a trivial time hiding and blending in. Most likely for the same reason, since there’s literally nothing we have that they could want other than to study us as a curiosity. The only resource we have that they couldn’t find easier and more abundantly, or reproduce from samples, is our culture. That’s it, that’s the only thing we have that might be considered with the effort. Not water, air, energy, precious metals, phosphorous, brains, mates, food, slaves, vassals, soldiers, or anything else that would be worth the trip.
