I would teach both evolution and creationism (YEC). The reason for choosing one over the other comes down to theological belief and understanding…not science. Science cannot answer philosophical questions well…it cannot explain God or why God does what he does. Example, the incarnation and salvation, can that be explained scientifically? Can science show us why Jesus had to die for sin? can science explain what the priest was really doing theologically when he laid his hands on the scapegoat at the end of the Day of Atonement Service? Can science explain God speaking every element of his creation into existence?
