The Design Argument is a philosophical reasoning that suggests the existence of an intelligent designer based on the complexity and order found in the universe. Proponents argue that just as a watch implies a watchmaker, the intricate systems in nature imply a creator. This argument is often associated with the works of thinkers like William Paley, who famously compared the universe to a watch. Critics of the Design Argument point to natural processes, such as evolution, as explanations for complexity without the need for a designer. They argue that features of living organisms can arise through random mutations and natural selection, challenging the notion that everything must have a purposeful creator.
