"People I've interviewed have called UFOs various versions of the ultimate problem to solve. Many of them don't believe UFOs, a term that just means something in the sky that the viewer can't understand and we're forged in alien furnaces, but they do believe these sites are something. Maybe there's something in our heads. Maybe there's a secret military craft. Misinterpreted planets, blimps, wavering stars, atmospheric phenomena. Swamp gas. Our collective ignorance all of the above organized into sky lights. But whatever they are or are not, people undoubtedly see these things that they can explain, talk about them, write about them, wonder about them. Sometimes people sing about them. Plenty have wrote lyrics about UFOs such as Ella Fitzgerald, two little men in a flying saucer."
