Citing, again, Ian Johnston

He claims to have proven species to species evolution, like this:

First, there is variety in the natural world (that is self-evident). Second, all living individuals must have come from a living parent (no one has ever been able to prove the contrary). And third, simple species were around long before more complex species (any inspection of fossilized sedimentary strata confirms this point).

Second is invalid in the modality must. The burden of proof rests not on alleged alternative possibility, but on alleged necessity. God almighty, if such there be, obviously (by definition) can create an individual without using the normal procedure of a parent or two.

Third presupposes that geological layers be accepted as temporal in successive small disasters, rather than local in one great flood. For which there is cumulative historic evidence outside Genesis too. But this point has been made over and over again by creationists, only some do not want this point to be made in class.
