The idea that a hostile alien race is going to arrive here and try to wipe the human race off the face of the earth, may seem like something out of a science fiction film, but it is actually a possibility. Many famous scientists and astronomers have actually expressed concern regarding the idea that an alien race may want to acquire the earth for one reason or another.
On the other hand, an intelligent alien race would more likely look at the earth as being an incredible oppertunity to view a civilization of intelligent beings evolve and advance. They would be more likely to make field trips here to do research, rather than attack us with everything they've got.
Perhaps inhabitable worlds in the universe are few and far between - and some alien races would stop at nothing from stealing one at all costs.
Still, I think that when we do make official contact with an intelligent alien race, it will be a diplomatic meeting, and not a hostile one.
