"What test can you postulate that would allow us to demonstrate the function of Intelligent design? How do I look at a subject and objectively prove that it "looks more like" intelligent design?"
A good starting point might basic common sense. Look at the shirt you are wearing. Can you tell that it was intelligently designed and manufactured? How can you tell that?
OK, so that's not quite a fair question because we know that people manufacture shirts. So let's take another example. Suppose you were walking along the beach and you see the words "E = MC^2" written in large letters in the sand. How would you go about determining if it appeared by random chance with no intelligence?
I am constantly amazed the baloney evolutionists use to try to discredit the theory of Intelligent Design. Can't be falsified? Then I suppose my theory that the words on the beach were written by an intelligent being can't be falsified either.
In a sense it can't. Unless I can show a video of a person actually writing the letters, how can I "prove" that the message wasn't a result of random wind effects? I can't. That is the kind of ridiculous standard evolutionist require for ID.
