This is so Carl Sagan.

And so we got to talking. But not, as it turned out, about science. He wanted to talk about frozen extraterrestrials languishing in an Air Force base near San Antonio, “channeling” (a way to hear what’s on the minds of dead people—not much, it turns out), crystals, the prophecies of Nostradamus, astrology, the shroud of Turin … He introduced each portentous subject with buoyant enthusiasm. Each time I had to disappoint him: “The evidence is crummy,” I kept saying. “There’s a much simpler explanation.” … And yet there’s so much in real science that’s equally exciting, more mysterious, a greater intellectual challenge—as well as being a lot closer to the truth. Did he know about the molecular building blocks of life sitting out there in the cold, tenuous gas between the stars? Had he heard of the footprints of our ancestors found in 4-million-year-old volcanic ash? What about the raising of the Himalayas when India went crashing into Asia? Or how viruses, built like hypodermic syringes, slip their DNA past the host organism’s defenses and subvert the reproductive machinery of cells; or the radio search for extraterrestrial intelligence; or the newly discovered ancient civilization of Ebla that advertised the virtues of Ebla beer? No, he hadn’t heard. Nor did he know, even vaguely, about quantum indeterminacy, and he recognized DNA only as three frequently linked capital letters.
