Which argument suggests that complex things, like the human eye, imply the existence of a designer?

The Design Argument posits that the complexity and functionality of various entities in the universe, such as the human eye, suggest that they have been purposefully designed rather than being the result of random processes. This argument is rooted in the observation that complex systems often have specific functions that contribute to their effectiveness, indicating an intelligence behind their design. The human eye, with its intricate structures and precise working mechanisms, exemplifies this complexity, leading to the inference that a designer must exist to account for such intricate features and their effective purpose in enhancing vision.

The other options do not adequately capture the essence of this argument. The Causation Argument focuses on cause and effect relationships rather than the notion of design. Scientific Explanations typically address phenomena through natural processes without invoking a designer. Criticism of Science challenges scientific methods or conclusions, rather than proposing an argument for design. Hence, the Design Argument is the most appropriate choice, as it directly correlates the complexity of organisms and systems to the implication of an intelligent designer.
