Some philosophers argue that all the subsets of evolution - genetics, mutations, natural selection could still support permanence of species with local changes. Until you can create an entirely new species in a laboratory without direct gene editing, there cannot be positive proof for evolution - but till that is done, there is no negative test that would disprove that evolution is the consequence of all its component hypotheses.
Personally, I don't see any reason to doubt evolution, considering it is neat and beautiful. But at the same time, I can see that it hasn't been built via the same scientific method seen in physics.
Being able to do that is no more positive proof of evolution than any of the more or practical tests. Also, speciation has been observed and created in controlled settings without direct gene editing (indeed, some before gene editing was even a thing), so if it was positive proof of evolution, we could mark that off as proven absolutely.
The “theory of evolution” is a large composite explanatory story wrapped around a large number of testable (mostly thoroughly tested) hypotheses. It's falsifiable by falsifying any of the components, though the replacement is liable to look remarkably similar but for who the falsified piece is addressed, and still likely to be called the “theory of evolution” even though the content is different.
