"The dictionary definition of design suits me fine. No need for science to give it a special meaning of its own."
Which one would that be?
(I note you have still refused to give a definition. I assume you don't know of one. If you can't even define design, how do you know it when you see it?)
Webster's. The same definition science uses when ascertaining the presence of the same. Both design and intelligence, as commonly understood, are within the scope of scientific endeavor. Therefore science is free to hypothesize and test for it whenever, wherever, and however it pleases. Science is not subject to your narrow definitions or constraints.
