the fall of the most stable governments, the huge riots that arose from the frantic attempts to get possession of the existing stocks of margene cakes or of the rare luxury items of other edibles, the announcement by the U.S.S.R. that it had known from the beginning the whole thing was a gigantic American hoax in the interests of the imperialistic bloodsuckers, the simultaneous atomic attacks by east and west, the Short War of 1970 that ruined most of what bombs had spared of the Earth, the slow struggle back of the remnant of civilization which is all of existence you and I have ever known—all these were a direct outgrowth of that first appearance of the margenes on the beach near San Diego on an April night in 1960. Marge and Gene Towanda were divorced soon after they had both lost their jobs. She was killed in the hydrogen blast that wiped out San Diego; he fell in the War of 1970. "Margene" became a dirty word in every language on Earth. What small amount of money and ability can be spared is, as everyone knows, devoted today to a desperate international effort to reach and colonize another habitable planet of the Solar System, if such there be. As for the margenes, themselves, out of the untold millions that had come, only a few thousand were lucky enough to survive and find their way back to their overcrowded starting-point. In their strange way of communication—as incomprehensible to us as would be their means of nourishment and reproduction, or their constitution itself—they made known to their kin what had happened to them. There is no possibility, in spite of the terrific over-population of their original home and of the others to which they are constantly migrating, that they will ever come here again. There has been much speculation, particularly among writers of science fiction, on what would happen if aliens from other planets should invade Earth. Would they arrive as benefactors or as conquerors? Would we welcome them or would we overcome and capture them and put them in zoos and museums? Would we meet them in friendship or with hostility? The margenes gave us the answer. Beings from outer space came to Earth in 1960. And we ate them.
