Possible Alien Signal Detected?

[GuernseyCard]

My Dad always said that if advanced life ever reached Earth, they would most likely just sit back and observe us for a while before they made contact, in which case they will probably put a Giant sign up around Jupiter that says; DONT GO TO THAT PLANET, THOSE PEOPLE ARE PSYCHOTIC SAVAGES WHO KILL EACHOTHER FOR RIDICULOUS REASONS. COME BACK IN 100+ YEARS AND REASSESS.

If they can get here, they'll view us as ants.
