Now, you are asking what isn't designed. That's a philosophical question, not a scientific one.
To state that DNA has the characteristics of design is not a philosophical question. It is a practical observation of nature.
Can you see the difference?
I will grant that saying everything is designed is far more useful -- it's the foundation of science in fact -- than assuming everything is by chance which is the paradigm that anti-IDist in effect advocate.
Classic science assumes design and attempts to find what the design is.
Energy detected in the physical universe comes from physical means. Have you ever detected or measured energy that derived from non-physical means?
No you have not.
If you say detecting design is a scientific question, then how could detecting things NOT designed not also be a scientific question by your flawed criteria?
Do you think that DNA is “more designed” or has more “characteristics of design” than other things in the universe? Are those other things any less designed by God?
Science, classic or otherwise, describes physical causes that are necessary and sufficient to explain physical phenomena. Nowhere in the history of science has the supposition of non physical causes led to anything of any productive use.
