Theistic Evolutionists have more in common with atheistic Evolutionists than just their creation myths. They even argue for it like an atheist would. For example, I remember one Theistic Evolutionist I debated who hung a large part of his case on our ignorance of nature, following it up with the example of the hyena's pseudopenis. To him, this is enough reason for us to credit Evolution, rather than just taking God at His word.
When refuting Evolution, I sometimes like to point to the coccyx as an example of their failures. Vestigial organs as a whole is a terrible argument that relies on ignorance. "We don't know what this particular organ does, therefore it is an Evolutionary leftover". With the coccyx, Evolutionists used to, and still to this day, argue that the coccyx is a leftover tail. As recently as 2017, the American Museum of Natural History had an exhibit claiming the coccyx "serves no purpose, but reminds us that humans have descended from ancestral animals with tails."
Any Creationist could have told you this is false. For thousands of years, the Bible has been telling us the Lord has a purpose for everything. Even the wicked have been prepared for God's purpose. The so-called tail bone actually serves multiple functions. It helps us to sit down comfortably by providing a third point of impact, it is an anchor point for 9 muscles we use during toilet time, and it even has a function during childbirth. We know this now because Evolutionists, in their ignorance, used to remove them from patients. Because of the persistence of the tailbone argument, it is entirely possible the practice may even be revived in the future.
In other words, Biblical ignorance lead to medical malpractice. In fact, of the 180 "vestigial organs" Evolutionists used to claim were without purpose, only a complete scientific dunce would use even one of them as an argument now.
As Christians, it should just be common sense that we should believe God's word, and that to stray from it so radically as to effectively say "no, the atheists have a point there, God is wrong" often leads to some of the most unpleasant consequences even in this realm. I wouldn't like to imagine what it's like explaining that to Him on judgement day.
If there is ever anything you don't understand about the world, that doesn't mean God is wrong, it means you are fallible. As human beings, we make mistakes. There are gaps in our knowledge, and sin taints our hearts. Of course we aren't going to understand the purpose for every single thing God does. Let us not concern ourselves with understanding every intimate detail of God's plan. It's His job to understand things He doesn't reveal to us. Our job is to listen to the things He has revealed. Ignorance is no excuse for heresy.
