Google is your friend. Perhaps start with Wiki:

A teleological or design argument[1][2][3] is an a posteriori argument for the existence of God based on apparent design and purpose in the universe. The argument is based on an interpretation of teleology wherein purpose and design appear to exist in nature beyond the scope of any such human activities. The teleological argument suggests that, given this premise, the existence of a designer can be assumed, typically presented as God. Various concepts of teleology originated in ancient philosophy and theology. Some philosophers, such as Plato, proposed a divine Artificer as the designer; others, including Aristotle, rejected that conclusion in favor of a more naturalistic teleology.
