You can't because the living thing is so far superior to the man-made manufactured thing that it's hard to make the comparison.
The last time I looked, manufactured things did not assemble themselves or reproduce themselves with variation and negative feedback.
That's right, and if those simple manufactured things are the result of intelligence and design, then the far superior living things that can do things unheard of compared to our simple machines, must have been the result of a far superior intelligence.
But you are missing the point. Things designed by evolution are different in almost every respect from things manufactured by humans.
The only real exceptions are manufactured things designed with the aid of evolutionary algorithms (copied from nature).
The future of design in complex manufactured goods rests with our ability to understand and copy evolution in our design processes.
