In chapter twelve, The Design Argument: Cosmic Fine-Tuning, Groothuis states there is enough design evident at multiple levels of nature to infer that there is a Designer. However, there is also evidence of deformity, decay and disease, indicating that the design is often less than optimal. Thus, there is enough evidence to believe in a Designer, but not enough to claim a perfect creation. There is enough deformity to warrant the idea of the fall, but not enough to deface the idea of design entirely.
