NSA releases documents proving extraterrestrial contact?

If you had actually looked at the document, you would have realized that it's a code game. Basically, someone made up a few codes based on math to see if anyone else could decode them to find the message, the idea being that aliens might try to communicate that way. It wasn't actually codes from space or from aliens. It was just a trial run of what we might get, and probably wouldn't, since all the transmissions we send out are in our languages which aren't based in logic.
