>>Scientific/biological inquiry into complex body parts, interconnections, and functions make up the basis for observing and concluding intelligent design. <<
No they don’t. Just because something is complex doesn’t necessarily mean it was intelligently designed. It just means it is complex.
>>ID is absolutely scientific.<<
OK, let us say you are a scientist. Show us how you would use ID in an experiment. Or in a conclusion. What tool will you build in the real world? How will you apply ID? How will your ID finding be reproducible?
Those are the practical, layman questions. The Scientific Method questions practically write themselves but I will let you answer these first.
Through the study and analysis of a system's components, a design theorist is able to determine whether various natural structures are the product of chance, natural law, intelligent design, or some combination thereof. Such research is conducted by observing the types of information produced when intelligent agents act. Scientists then seek to find objects which have those same types of informational properties which we commonly know come from intelligence. Intelligent design has applied these scientific methods to detect design in irreducibly complex biological structures, the complex and specified information content in DNA... -- http://www.intelligentdesign.org/whatisid.php

You make good points.
Substitute evolution for ID and the same questions apply.
