I think a race capable of space travel would not be interested in us (except maybe for scientific study or an interstellar, reality-TV show) or our planet. If they can live in space they'd likely prefer space to our gravity well.Of course that is possible. But without having any idea of what is actually out in the galaxy, we are only guessing. It would be great if super advanced aliens wanted to help us for no reason other then to help us.Possibly. But I see that even we understand conservation of species in which we are curious. A civilization so advanced as to be able to travel that far may also have discovered these ethical and moral ideas.The reasons for them coming here would probably not be good for us.
But all civilized beings will have some societal structures that are common to others. Like a ruling class, a science class, etc. We do not have any idea if any advanced race exists, or if advanced races are common place and we, being unable to venture out, cannot see them.
That being said the possibilities are endless. They could appear and help us because they want to lift us to their level to help mankind. Or, they could be involved in a galactic power struggle with two or more advanced species and when they expanded to here, because we are close to their enemies in the Davaroni sector, the Davaroni's could swoop down on us to claim our planet as a forward operation base to keep the other ones from encroaching on them.
And conscript a bunch of us as workers with all the ramifications that would have.
