You are mixing the science those people support with their personal beliefs. I’m sure if you nailed them down on their scientific beliefs, they would be forced to admit that the theory of evolution is a product of naturalistic science, which begins with the premise that science cannot account for, postulate, or attribute phenomena to supernatural causes. Therefore saying that you believe God created evolution is essentially saying that you believe God created a process described by a theory that does not admit the possibility that God created it.
The process is the process. Nothing in evolutionary theory speaks about who or what created the process, or if it needed to be created at all. The first life came from somewhere -- it could have formed through naturalistic mechanisms, it could have been zapped into existence ex-nihilo by a deity -- evolution doesn't try to tell us what happened.
Conflating the methodological naturalism of the scientific method with the philosophical naturalism of atheism is a common tactic, but it only works as long as people don’t know they aren’t the same thing.
