Don't worry, if there's some kind of galactic order, it's almost guaranteed that they'd want nothing to do with mankind at this point in our evolution.
I hope so! My larger concern would be a single, super predator race. Ignoring human ideals and morals, surely the safest thing for a race that’s vastly ahead in technology wise when finding a younger race to do would be to just wipe them out, no? Why would they risk letting humanity catch up in technology and having diplomacy potentially fail? Hopefully they’re interested in observing or working with other life forms, but if they’re not in my mind them pressing the delete button is the obvious option.
I'll put it this way; You really only go out of your way to eradicate an ant mound if they're in your backyard, and there seems to be quite a bit of wilderness between "backyards" in this sector of the galaxy. Well, so far, at least. If we get another 'Oumuamua in my lifetime, I'm gonna start thinking otherwise.
