That sort of successful lab experiment would refute the theological concept that useful DNA code organization has to come from an intelligent designer.
It would not, however, preclude an intelligent designer from organizing DNA code.
It wouldn't ... just because humans can do something or a reasonable facsimile thereof doesn't mean there couldn't have been a creator that did the same thing ...
It might show a creator wasn't required, but it couldn't show a creator didn't happen.
But, at least it was an ATTEMPT at trying for potential falsification of ID ... and that's more than I usually see on these threads.
(How DO you falsify a creator ... or, let's put it bluntly, God? Would you even want to?)
