Most IDiots are half-a-century behind in their knowledge of science. They think that random mutations and natural selection are the only way that evolution can occur.1 That's why they refer to evolution as "Darwinism."
Many of them have heard vague rumors of change, proving that from time to time they do, indeed, take their fingers out of their ears. They've discovered that modern scientists have moved well beyond natural selection as an explanation for every bit of evolution. This makes the IDiots very happy since, to them, it means that evolution is wrong. And if evolution is wrong then gods must exist.
They've even developed a course to explain why Neutral Theory and random genetic drift support the idea that gods must be making bacterial flagella and protein-protein contacts. It looks like a very interesting course ...
