Watching The Outer Limits - s02e9 - Trial by Fire, I find myself wondering somewhat just what kinds of civilizations we could find out there amongst the stars.
Based on our own civilizations throughout history, I rather think there's three ways that works out.
In a perfect world, we would probably have a first contact out of Star Trek. But I don't really have that high a hope for humanity, so I expect our early associations to look more like Avatar or Enemy Mine.
In a way though, I worry that a more likely scenario given how difficult truly foreign beings are, and how fucked up we are, things would turn out more like the Earth-Minbari war in B5. Which could be summarized as a hot head meets cultural differences kicks off the near extimerination of the human race. Except I don't think the Battle of the Line would turn out so fortuitous, so much as like an ID4 assault ship firing its primary weapon.
