[General] Earth has been invaded by aliens numerous times in books and movies over the years. However, what are some actual reasons an alien race would have to invade earth?

Other than just being in the mood to conquer a planet and be an evil antagonistic force in general, what would Earth have that would cause an alien force to invade Earth?

I can only see that they would do it because they see a worth in our biosphere, or some kind of interest in us as intelligent beings, for some reason. Resources themselfes are plenty in space, and you could probably get them from shallow gravity wells compared to ours. Also, even if they wanted some natural resource from Earth that wasnt biological, why not just bomb us from orbit without actually invading and then pick up whatever they want.
