my mind went to the voyager satellite now billions of miles out beyond our solar system. If my memory serves me there is a bronze or brass plaque attached. Engraved are the words “We come in peace”. That one phrase ought to alert any sentient beings capturing the probe to recognize that from where the satellite originated the creator is tainted. If it knows peace then it knows war. And therefore likely practices good and evil. Planet Earth included a star map, a trail to find us.
