Question: How did making contact with aliens bring an end to poverty, disease, and war? Even after the Third World War, there still would have been millions of people who wanted wars on earth, and they would find ways to commit attacks that would start wars on earth, and get away with it, by pretending to help bring an end to wars, poverty, and disease, by secretly stealing alien technology, and by attacking homes, and destroying replicators once every citizen on earth had one, and by telling the aliens to leave earth and never return, and they would have been no way to catch everyone who wanted wars on earth.
