Creationists often charge that a design necessitates a designer. But I think they have this backwards. A watch may have a watchmaker, but watchmakers don't exist ex nihilo. To get a watchmaker takes so much R&D, both in terms of developing an organism capable of making watches as well as all the knowledge required in order to build a watch. In other words, the designer is designed.
Design doesn't necessitate a designer, but a designer necessitates design.
