As I said in my previous post, you are looking at it from the wrong perspective. You are not the audience. That it does nothing for you, or for the objective truth of the claim is totally irrelevant. Creationist aren't trying to persuade the average person on the street to change their mind, they are trying to protect the view of fundies from attacks that might cause them to lose faith. It is more about holding what they have than winning new converts.
The audience is fundy Christians, and it plays well with that audience. That is all that matters. It serves a purpose to justify and validate a pre-existing worldview among a small section of society, and these are the people being spoken to.
From this perspective, it would be wonderful for the apologists. In this hypothetical scenario, I could design a wonderful communication strategy for creationist that would strike a chord with my intended audience. Would be an absolute dream PR scenario for the creationists, like shooting fish in a barrel.
