Even from a scientific perspective, evolution is untenable. It is both bad theology and bad science. The theory is obsolete; it only persists because it is a basic tenet of faith in humanism/atheism. Since the unraveling of DNA we now understand that the mechanism behind the development of enhanced function in cells and organs is not a random physical process. It requires a highly complex set of instructions. That is, it requires highly complex instructions that are forward looking, purposeful, and goal oriented. The information presupposes a perfectly detailed end product. The mechanism is the exact opposite of the randomness of evolution. The question is now, “where does the information come from?” There is no known physical process for creating “intelligent” instructions. The only known source is a mind.

I would say that evolution is better as theology than it is as science, but the untenability of it comes in part from the inability of its followers to recognize that.
Evolution is a theory of origins. Evolution is a theory of meaning and purpose. Evolution requires faith in something outside of and beyond us. It tells a great story. As theology, evolution is excellent, compelling, and gripping.
There are just two problems:
1) Like all other false religions, evolution might make for an exciting narrative, but it is dead wrong - an inaccurate, hopeless, and ultimately damning worldview.
2) Evolution is TERRIBLE science, and its followers are unable to see that it is a theology and not a science.
I would have more respect for evolutionists if they called their belief a religion and admitted the faith presuppositions that undergird their belief in it as that - faith presuppositions.
Lastly, as with all other false religions, attempts to syncretize evolution with Christianity are not viable. Some people reject the theological tenets of evolution and try to combine its scientific findings with Christianity, but since evolution is ultimately a religion, its scientific "findings" are rooted in a theology very much opposed to the theology of Scripture. As a result, all such marriages of the bad terrible pseudo-science of evolution and the truth of Christianity are going to be quite uncomfortable.
You can believe in day-age, gap, framework, or whatever variant interpretation of Genesis 1 you want, and they might be inconsistent, but only evolution in any of its varieties presents a premise that cannot be reconciled in any way with the account not just of Genesis but of all of Scripture. That said, the popularity of those other beliefs stems, I suspect at least in part, from the success of the evolutionary narrative in discrediting or rendering unfashionable a more literal reading of the creation account. If you take away evolution and its direct and indirect influence, you have a lot less motivation to believe some of those other takes.
