Nail, head etc.
I have no problems believing in God and, at the same time, accepting the theory of evolution. I have no need to prove the existence of God to anyone- I accept it on faith. I do have a need to see evidence before I accept a scientific theory, and I haven't seen anything with better evidence to explain how we got here than the theory of evolution.
The problem that most theologians grapple with is that if evolution were true, there would have been no reason for Jesus to die on the cross.
A foundation of Scripture is the plan of salvation that Jesus completed on the cross with His sacrificial death and His subsequent resurrection. Thus conquering the death that Adam made as a Free-Will choice in Eden. Adam's choice to forfiet his inheritance to Satan, brought about original sin, as well as the curse on our universe.
To make it short, evolution blows all of these scriptural doctrines out of the park, leaving an empty husk of lies and half-truths. This is why Biblically literate believers completely reject the idea that God used evolution to bring us to this point. It contradicts the whole of the Old and New Testament writings.
