If you haven't heard, the Vatican says that the possible existence of aliens doesn't hurt Christianity. Last night, Stephen Colbert talked about it.

I like how Colbert can do a little funny rant on a topic but then get a serious guest to discuss the topic and bring up some very interesting ideas. And like most Colbert rants, it somehow manages to get other pop culture references in, including Jabba The Hut, the ShamWow, and James Cameron.
