Sagan marvelled at the cosmos but found no evidence of design — only natural processes producing grandeur without purpose.

Carl Sagan was perhaps the most eloquent populariser of science in the twentieth century, and his response to the design argument was characteristically poetic and devastating. He found the universe staggeringly beautiful and awe-inspiring — but he saw no evidence that this beauty was designed. The cosmos, as he described it, is vast, ancient, and indifferent.

Sagan pointed out that the universe is overwhelmingly hostile to life. Billions of galaxies, each containing billions of stars, most orbited by lifeless worlds or no worlds at all. If the universe was designed for life, it is an extraordinarily wasteful and inefficient design. The scale of the cosmos — 13.8 billion years, 93 billion light-years across — dwarfs any conceivable purpose centred on one species on one planet.

His famous 'Pale Blue Dot' passage captured this perspective: Earth is a mote of dust suspended in a sunbeam. The design argument, Sagan implied, requires a cosmic narcissism that the evidence does not support.

Key quotes

> “Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.”

> “Extraordinary claims require extraordinary evidence.”
