This sort of thing is why I believe that if there are space faring civilizations out there, they won’t come here intentionally.
Virtually everything that exists on earth, exists in vast abundance all across the universe and its all there for the taking. That only leaves a few possible reasons to visit earth. Scientific curiosity, they’re looking for friends, or they’re hungry for animal flesh.
There are plenty of reasons — they might come for political reasons, for example, they may have the equivalent of a Malthusian jackass running things. They may have been in expansion for generations already, and don’t know any other life. The presence of resources is a great reason to go places.
