Extraterrestrial life must exist. Don't know when we will discover it, but I hope its me! ($$$) Ee should not send out a beacon. Could be dangerous. Could be Prosperous. It'd be like giving out your address to random people on the street and "HOPE" that only the kind hearted come over for tea...I'd expect a party crasher, just because I like to be prepared ;) But then again, you'll never know anything unless you try and take a chance.
