The argument from design is an argument for the existence of God or a creator. According to the argument, the appearance of design in nature is evidence for the existence of God. The argument is teleological, because it assumes a purpose. The word "teleological" comes from the Ancient Greek telos, which means "end" or "purpose".

Teleology assumes there is purpose or direction in the works and processes of nature. Immanuel Kant called this argument the physico–theological proof.
