What is in conflict with Christianity is a materialistic worldview and the idea that matter and energy are all that exist. Philosophical naturalism is really the cornerstone of Darwinian theory along with the assumption that all biological information ultimately arose through random chance and natural processes. It is the religion of Darwinism rather than evolution per se that is in conflict with Christianity. And it seems to me very clear that at some very basic level, evolution as a scientific theory makes a commitment to a kind of naturalism, namely, that at some level one is going to exclude miracles and these sorts of things come what may. There are also a number of good reference quotes and articles in the science section of our library and a number of excellent books on our recommended reading page.
Science is restricted to the study of natural phenomena.
Therefore, it is assumed that creation events did not take place. This is not very logical, of course, but it is what the thinking boils down to. Most scientists simply begin with the assumption that the origin of the universe, the origin of life, and the origin of biological diversity and complexity must be explainable without recourse to intelligent input from outside the Cosmos. Others falsely conclude that no creator is necessary. The conclusions do not flow from the data, however.
