Are we worth saving?

Well, it's hard to know how aliens would judge things, but basing it on how I think, then no. I would look at humans and think of them like a parasite - plundering the planet, taking what we need and giving very little back.

This is interesting. I've always thought about this in a way too. Like you see in movies these aliens are not giving humans the light of the day and keep on killing them like nobody's business. Think along the lines of Anaconda, Predator and whatnot.. Makes me shudder to think, but last I check, there are no aliens behind me lurking. LOL.. I've yet to watch the movie Knowing. I heard it's such a good one from Nicholas Cage.
