Television allows us to transmit images of ourselves that propagate into space. The earliest of these transmissions have by now reached all of our neighboring star systems. None of these transmissions, so far as we know, has been recognized; we have yet to receive any messages of extraterrestrial origin. We must conclude that there is no extraterrestrial intelligence in any of our neighboring star systems. The reasoning in the argument is questionable because the argument ['assigns too little importance to the possibility that there is extraterrestrial intelligence beyond our neighboring star systems', 'neglects to mention that some governments have sent meticulously prepared messages and recordings on spacecraft', 'infers that there is no extraterrestrial intelligence in neighboring star systems from the lack of proof that there is', 'overlooks the immense probability that most star systems are uninhabited']
