As a graduate student at Yale, I studied the whole of Christian theology but focused my attention on the Darwinian controversies. I wanted to get to the root of the conflict between Darwinian evolution and Christian doctrine. In the course of my research I learned (to my surprise) that biblical chronology played almost no role in the 19th- century controversies, since most theologians had already accepted geological evidence for the age of the earth and re-interpreted the days in Genesis as long periods of time. Instead, the central issue was design. God created the cosmos with a plan in mind. This affirmation is among the most basic in all of Christianity (and other theistic religions as well, including Unificationism). And that plan included human beings as the final outcome of the creative process: we are created in the image of God.
This whole thing reminds me of when it was first perceived that the earth went around the sun. Perhaps in another thousand years ...
