Lio by Mark Tatulli for September 26, 2017

Various SF authors have posited that the reason we haven’t been contacted by advanced alien civilizations is that we are for some reason “off limits” to the galactic family of societies. In “Day the Earth Stood Still” we were even regarded as dangerous, possible candidates for destruction lest we contaminate other inhabited worlds with our warlike tendencies. C.S. Lewis, Protestant apologist that he was, suggested that though the human race was a “fallen” species, that other worldly people might not be. His idea was that God might have told the aliens to keep away from sinful humans for their own good. Interestingly, this is why Adam and Eve were warned away from the fruit that gave “knowledge” of good and evil according to Genesis. I wonder which writer first proposed the idea that we were cosmic outcasts because of some human fatal flaw. Anyone know?
