I been readin’ ’bout how maybe they is planets peopled by folks with ad-vanced brains. On the other hand, maybe we got the most brains … maybe our intellects is the universe’s most ad-vanced. Either way, it’s a mighty soberin’ thought.
Walt Kelly (1913-1973) American animator and cartoonist [Walter Crawford Kelly, Jr.]
“Pogo” [Porky Pine] (20 Jun 1959)
Often paraphrased: "Thar’s only two possibilities: Thar is life out there in the universe which is smarter than we are, or we’re the most intelligent life in the universe. Either way, it’s a mighty sobering thought."
