Not really sure it’s a threat refuting the existence of God.
Sometimes a science thread is just a science thread.
It's irrelevant to the origins of life debate. The odd thing, however, is that the materialist reductionists will argue that this sort of thing is evidence for evolution rather than design, because what scientists have been able to do in a lab with cutting edge science and equipment -- which place the scientist in the role of the designer -- might be done accidentally by nature through random mutation. Or so they assert.
Someone should do a science fiction movie in which our intrepid explorers land on a planet of robots. On this planet, the robots would mock the idea that they are designed, because that would imply a designer and possibly a governing purpose. They find this objectionable. They would acknowledge that there was an ancient robot legend of a designer and a prime directive, but they have rejected that in favor of the proper theory that they are the products of hurricanes hitting junkyards over eons of time.
When asked where the junkyards came from, they would reply with a multiverse theory that asserts that in an infinity of universes over an infinity of time, everything that can happen must happen, and some universes create junkyards. This is scientific and not a legendary "just so" story because it dispenses with the objectionable hypothesis of a designer.
Westworld could tiptoe up to these themes. If Michael Crichton were still alive, it probably would. The showrunners seem to have a different agenda. To date, it the show is treating conscience as an emergent property of complex systems, which is a contemporary reductionist device for "explaining" something by naming it.

"Well, you know how it is, Charlie
Brown. You win a few and you
lose a few."
"Sigh. Wouldn't it be nice?"
“Sometimes a science thread is just a science thread”
Had that in mind as well. Point being that even a complete understanding of the genetic code is just a baby step toward mastering the process of creating life. Even a bacterium is astonishingly complex, and much of that complexity is dedicated to the making of new bacteria. DNA is just a piece of that.
