They will not bother to do anything with us. They see us as a primitive civilization that wages violent wars over "resources" on our planet. At the same time our universe has billions and billions of "earths" that exist for a much longer period of time.  For a civilization so advanced and so intelligent visiting earth and dealing with us it would be just a waste of time. We are simply stupid for them. We all know that everyone, with at least 2 gramms of brain, avoids stupid and violent people.,(reply>), The aliens would realize that people are intelligent, and not at all primitive, and not at all stupid. They may have some additional technology, but at this point people are well past the primitive stage.
