Paley's proof for the existence of God
P1. A watch has certain complex features of spatial order and purpose
P2: Anything which exhibits these features of spatial order and purpose must have been designed by a designer
C1: Therefore, the watch has been designed by a designer
P3: The universe possesses features of spatial order and purpose, except on a far more wondrous scale.
C2: Therefore, the universe has been designed by a wondrous designer
C3: Therefore, God exists.
