Then they are creationists in the vague sense that "God created something somehow some time ago", rather than the more common and specific meaning.
I do not believe the Earth was created 6000 years ago and I do not believe in evolution. So what am I according to you?
Because we are multicellular organisms.
What about it? Creationism, as I see it, is incompatible with evolution: the former asserts that the various species poofed into existence as is ~6000 years ago, while the latter asserts that all life on Earth is descended from a single common ancestor that lived ~3.5 billion years ago.
Theistic evolutionists, then, are those who believe in the scientific theory of common descent, whilst still ascribing some 'divine creation' role, usually in that God created the universe (but species developed naturally).
I believe both of these views are naive and based upon less than zero evidence.
Indeed, though I've yet to see someone reject evolution who wasn't a) ignorant of the evidence through no fault of their own, b) intellectually incapable of grasping the theory, or c) a zealot who rejects the theory on religious grounds.
I reject evolution on scientific grounds. There is nothing in the Bible that is opposed to evolution. Rather it is observational and physical evidence that contradict evolution.
"...Evolution makes the strong prediction that if a single fossil turned up in the wrong geological stratum, the theory would be blown out of the water. When challenged by a zealous Popperian to say how evolution could ever be falsified, J.B.S. Haldane famously growled: 'Fossil rabbits in the Precambrian.'" -- Richard Dawkins, biologist, 2006
Fossil octopuses in the Cretaceous represent a single fossil in the wrong geological stratum.
Therefore evolution is empirically falsified.
And if you don't believe that's true, then it's obvious you don't believe evolution is scientific since it cannot possibly be falsified by evidence.
"Darwinism is not a testable scientific theory, but a metaphysical research programme." -- Karl Popper, philosopher, 1976
The universe approaches the limit of infinite age. Claiming that the universe is only 14 billion years old contradicts observational evidence.
