The reason for the promotion of evolution is to release man to live any way he pleases without regard for any God. It is an amazing thing to me that it is the Christian who tries to accept evolution and insert it into Genesis somewhere. Evolution is not a proven fact. In fact, it isn't even a good theory. It takes much more faith to believe in evolution than it does to believe in creation.
Evolution is based on uniformitarian philosophy.
Put more simply, nothing in the past has ever happened at any other rate or in any other way than it is happening today. Therefore if sediment is only being produced at the bottom of lakes a few millimeters a year today and the sedimentary layers are a certain thickness today we can go backwards and tell how many years it took to produce them. Noah's flood could do in a few hours what natural sedimentation at the bottom of lakes would take millions of years to do. There are all manner of marine fossils that cover many square miles of the Tibetan plateau which is far, far above sea level today. Trees have been found fossilized upside down in layer after layer of sedimentary rock.
