the.com/argument from design

means The argument that the universe's complexity and apparent order imply an intelligent designer, much as a complicated, purposeful object implies a maker.

from The classic formulation comes from William Paley's 1802 book 'Natural Theology,' where he imagined finding a watch on a heath and reasoning that its intricate parts, working together for a purpose, demand a watchmaker — unlike a stone, which needs no explanation. The reasoning itself is far older, traceable to ancient Greek and medieval thinkers who pointed to cosmic order as evidence of divine craft, but Paley's watch became the image that stuck, later famously challenged by Darwinian evolution as an alternative explanation for apparent design without a designer.
