Actually, it is both discovered and created, as we find with all human endeavors which are embedded in the natural systems. The problem has been where the demarcation line ought to be placed (fuzzy existence). In an operational sense, many of the choices taken to resolve the problem work. Of course, some better than others.
A larger ramification? When choices have a large sphere of influence, then more care is needed. Unfortunately, we have gotten to the point where "care" is not part of the model (lots to discuss in this regard).
Beside pointing to the quasi-empirical issues, we'll weigh in, soon, with a novel approach, on the question in the title of the post.
In the meantime, see the recent renewal of faith.
