Talking to whoever’s out there

Last week The Economist reviewed The Eerie Silence by Paul Davies and mentioned at the end of the review a contest run by the Daily Telegraph asking what message people would broadcast to aliens. The Economist then quoted this suggestion:

“Two thousand years ago, we had a very enlightening visit from the Creator’s Son. Has he been to visit you yet?”

Now, I thought that was a pretty cool message to the unknown. What would you send?
