A Polygon writer set out to identify the single greatest panel from Bill Watterson's Calvin and Hobbes, the beloved comic strip that ran in newspapers for a decade. To qualify, a panel needed to feature both Calvin and Hobbes together, capture the strip's blend of humour, philosophical musing and heartfelt adventure, and stand alone outside its surrounding strip and the wider Sunday-strip format that often broke from typical comic conventions.

The writer settled on a panel from 9 November 1994, set during one of Calvin and Hobbes's woodland adventures, in which Calvin muses, "Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us." The choice highlights Watterson's detailed, painterly depiction of nature alongside his simply drawn characters, and reflects the writer's view that the strip's best moments combined comedy with genuine philosophical depth rather than pure gags or sentimentality.
