I'm not "pretending" anything, and you're clearly missing or avoiding the point. I'm using the "insulin-producing bacterium" as a real-world example of intelligent design. Ask any diabetic: it's most likely how their insulin is produced.
The utility of the example is obvious: is "science" up to the task of recognizing the presence of a designer in a case where we already know the correct answer? An answer either way has some fairly broad implications, which I've been addressing on this thread. That's not "pretending," narb -- that's just plain old rational thinking.
I think any fair minded lurker can conclude that you dare not acknowledge the real definition of ID because you would be forced to claim that your "designer" is God.
LOL! How very ad hominem of you. A "fair minded lurker" would not come to any such conclusion, unless they weren't really fair minded after all.
You are transparently desperate to change the question away from "where did the designer come from" to "can life be intelligently designed". This allows you to avoid acknowledging that your designer is a supernatural being, and thus ID is not necessarily a religious faith.
If complex structures can only be the result of intelligence, then logically the only way a designer can exist is if he/she/it is a supernatural being, because ID proposes that no complex entity can exist without being designed. An inescapable logical loop.
But lets assume that some non-supernatural entity designed life and planted it on earth. A space alien if you please.
Since ID proposes that complexity can only be the result of intelligence, then who designed the physics of chemistry on which life is based? Certainly the nuclear forces, relativity rules, quantum mechanics, electrons, protons, all the other weirdly named particles that are all interdependent on one another are complex in and of themselves. Who designed them?
Again, if there is a designer, then he/she/it must have designed the rules that operate the universe itself, and all the matter therein, and must by definition be "supernatural".
Perhaps there is such an entity. But if so, he/she/it not only designed life, but the existence of the natural universe itself. And the evidence we find left behind in that natural universe of how life operates and changes over time science calls "evolution" and it's been going on for several billion years.
