The Darwinian speculative thesis of random errors filtered by natural selection explaining anything substantial in biology is simply, completely, and astronomically out of the ballpark of plausibility.
In our engineering department (software, hardware, electrical, mechanical, aeronautical) we have a phrase: Does the proposed solution pass the beverage-out-the-nose test? (Meaning, of course: Would the proposed approach have any possibility of success?)
The problem with most Darwinists is that they have no real-world experience in any hard-science discipline with real-world accountability (such as engineering), in which a proposed solution or mechanism must first pass the beverage-out-the-nose test, and then be empirically verified to be capable of what is claimed for it.
Storytelling doesn’t cut it in real science, but that’s basically all Darwinists have left, especially in light of the fact that the underlying mechanisms of living systems are fundamentally based on the most sophisticated computer program ever written.
