On a more serious note a message to intelligent lifeforms in our galaxy should read more like this
HELP!
We are the human race, an intelligent lifeform in the milky way galaxy.
We wage mindless wars with each other. We are having difficulty integrating our own ideologies.
We are having trouble living in our own natural world. We harm it, only taking steps, when we are in dire need of taking the right course of action.
Over one billion people have lived in extreme poverty for 100 years on our world.
We are having difficulty coming together as one race, the human race. For all of our failings we are at heart a good people.
We will save a drowning man, at risk to our self. We are capable of great compassion and love.
Amazing inventions we have created.
And most of all we are capable of forging a lasting friendship. An alliance between us and other intelligent lifeforms in the milky way. An alliance built on trust to live in harmony, helping each other. Working together. Living together.
Their return message, "Join the universal club of life." Intelligent alien talking: "It's called, in your terms, 'differentiation' and 'the branching tree of evolution.'. Also 'complexity' and 'chaos'. Also, 'Life is always beautiful' (always from a distance) but never look at it too closely because it is also ugly (it is also various beyond any want to comprehend). Also, a Utopian world is stone monolith, no energies, no revolutions, no evolutions, no creations, no exodus (no expanding universe), really no rounding of life, in it, Un-free. Un-liberated. Unintelligent (As J. Hector St. John de Crevecoeur said, among many others, 'contracting' / 'contracted', 'no development of mass genius' (no opening and expansive frontier state . . . including of the mass mind)), Savage. Tyrannical. Anarchic. 'Dark Age' Un-civilized." (The physics, "What cannot or will not divide outwardly more benignly, will divide inwardly more malignantly!")
