is there any case for Intelligent design in man made products

Your point of course is irrelevant to the issue of the nonsense con job called Intelligent Design.When dealing with man made products there is ample evidence of the Intelligent Agent.If and when the con men trying to market Intelligent Design present evidence as convincing and overwhelming for the "Intelligent Agent" in "Intelligent Design" as is available for the "Intelligent Agent" in human designed products then, and only then, can "Intelligent Design" be considered anything more than a joke.BUT WAIT...there's more.We also have pretty convincing evidence for both the model and method involved in designing and influencing man made products. In fact, there is so much evidence in support of human design that there are even schools that teach the model and method.

Not quite.Natural selection is simply the environment.It really is that simple.
