Well, we kill each other over oil, money, different religious view points, alternate sexual identity or attraction, different skin tones..you name it. If someone seems too different to us for comfort, then we feel compelled to control them. If we can't control them, we kill them. In today's world understanding and compassion seem to be seen as weakness. You can say these shows show the worst side of humanity, but they also tend to show at least one person trying to do the right thing. So, they do show that humanity has a good side as well. There wouldn't be much of a conflict otherwise, I guess. But, if we do this to each other as humans, what would we do to a race of aliens? The behavior displayed in this episode seems likely to me.. That is "kill 'em all"..unless they have bigger guns!

i would be fun to see an humaniod form to similar to us.. in this episode.

i never read the description of any episode. why would i?, it spoils the mystery of the episode itself.

my problem is why the aliens didn't use the emergency beacon..
