I'm a lifelong Christian--at least, as long as I can remember--and I first began studying the controversy over evolution over 50 years ago.
Evolution is proven. (Independently, twice over: by Darwin and Wallace in the 19th century; and on a new basis in the last half century, since Watson and Crick explained the molecular basis of genetics.)
But of course, the point of myths is to use storytelling to convey serious underlying ideas, usually about humanity and our relationship to the universe. And the two creation myths in Genesis do that very well.
What needs to "fade away" is the silly idea that the story elements of a myth are literally true, and the even sillier idea that they were ever MEANT, by the storytellers, to be taken as literally true. That is a new idea, apparently cooked up in the 19th century, and seems to have been inspired by some notion that Christians ought to behave as stupidly as atheists accused them of behaving.
The myth we need to get rid of is the new myth that claims functional illiteracy is a valid approach to the Bible (or, for that matter, to anything).
