If these objects in fact come from other worlds, which based on what little we hear is highly plausible, we (the human race) might be f*cked.
Just think about the level of technology required to travel to another planet, who knows from where but certainly millions of miles away, fly around at will and return home! If these are in fact extra-terrestrials, and if they are hostile, we don’t stand a chance against them.
