I don't think anyone has asked this yet, but what about [b]aliens?[/b] Is there any life out there other than humanity? If there is, are they limited to non-sapient creatures and single celled organisms? 

Wes would totally punch an alien in the face if he could. Screw first contact scenarios. Those grey, beady eyed sectoids need a show of who's the boss.

Its mentioned very slightly in the OP. But in general, humanity has met no major sentient alien life forms. While plenty of Alien fauna and wildlife have been identified and marked, there are for all intents and purposes, no intelligent alien species. That we (as the UEE) know of.
