This might be a good opportunity for you to clarify what evidence is necessary for you to conclude that an entity exists as a result of intelligent design. How do you know, when you see a "man-made" object, that it is man-made?

Didja click the links? AndrewC and I went over this already. Go read and come up to speed. We identify objects of unknown origin as man-made by comparing them with other objects of known origin--man-made and naturally ocurring.

I assume that you agree with him that there is a way to determine design in living organisms. How does one do so? Do you have examples of designed and undesigned organisms against which we can compare unknown specimens? Or is there another way?

We once had a very interesting thread on this: The Design Inference Game.

I can understand how comparisons are of value in determining the presence of intelligent design or not. What I am asking is, when the comparisions are made, what attributes of the object lead to the observer to a conclusion?
