 Okay, well, first of all, I do not believe that we should advertise our existence in outer space with radio for precisely the reason that you mentioned that perhaps the aliens could be dangerous. And then the question is, could they be evil? Well, that's actually not the point, because what happens if the aliens don't care? When we go into the forest and we see ants in an anthill, we don't talk to the ants. What do we do? We just pave them over.
