Exogenesis is a theory that states that life on Earth originated from extraterrestrial microorganisms that came to Earth on meteors and comets during the Late Bombardment Event. Even if this theory is true, billions of years have passed since then. Even if life was originally alien, it isn't anymore because it evolved on this planet.
We could be aliens to beings on another planet, but to us, we would not call ourselves "humans" if we were aliens.
Not Really there from another planet there aliens to us.

First of all, ask yourself "Are there really aliens?", "Has anyone REALLY seen an alien?". After you've gotten the answer, then you can begin to ask if aliens kill. But to answer your question, if there are really aliens, the question of whether they kill or not, will depend on what they think of other life forms. Are they superior to them? Can they be anihilated? In a nutshell, more questions, lead to more questions, but the ultimate question remains...do aliens really exists?
