ID v Evolution

In “The Lastest Proof Bush is an Ape,” Irish Pennants, says:

Intelligent designers see order in the universe, and conclude it must have a designer. Critics are correct to note that this is an epistemological, not a scientific conclusion.

Darwinists see order in the universe, and conclude it all happened by accident. But this, too, is an epistemological, not a scientific, conclusion. And an illogical one.

Why is it illogical?

While there is plenty of evidence of variation within a species and speciation within a genus, there is zero evidence — plenty of theorizing, but zero evidence — of one class, order or phyla becoming a member of another.
