How can we expect Aliens to land, and to get along with them, when we cannot even get along with ourselves?

While walking with my dog through the neighborhood, we pass a house where we hear yelling and screaming of the worst sort. These folks are being very angry and disrespectful to one another. As we pass, they stop screaming and stare at Pitch and I walking by. One of them smiles and waves, as if to say, “Hello Friend”.

Despite that friendly gesture, I have no desire to meet or hang out with these folks. They certainly would be foolish to think that I could make all their problems disappear.

Is there any reason to believe that Extraterrestrial Aliens would be any different? Why would they make contact with us when all we do is kill each other?
