Sci-Fi Noobs

You know the Sci-Fi movie you're watching has been written by noobs when you hear this statement: "You're trying to stop a civilization 200 light years more advanced than our own!" It's nice to know that in the future they'll be measuring how advanced a civilization is in distances, rather than in their accomplishments, or time. I just wonder how many light years more advanced we are than our primative ancestors of 2 million years ago! Maybe only half a light year ... how mong does it takes humans to walk that far again? :-)
