I recently joined a Facebook group that explores evidences for creationism. The group is composed of members with many different views on creationism, but the two most vocal are Young Earth Creationism (YEC) and Old Earth Creationism (OEC).
The debates that take place are often acrimonious and based upon simplistic understandings of science and theology. In one such thread there was a discussion of God’s creative acts which, to put it simply, states that because God does miracles that are instant (healing the deaf, blind, and lame), then the creation of the universe was also instant or did not take a long period of time, as in millions or billions of years. Advocates of this view associate the miracles in the Old and New Testaments with God’s creative acts in Genesis 1, to make the case that God didn’t create over millions or billions of years. The creation of the universe is therefore deemed a miracle because it happened quickly. It could not be a miracle if it took millions of years. YEC advocates generally agree that creation has the appearance of age, but is actually young—in the 6,000 to 10,000 year range. OEC advocates say that the universe is ancient and looks old for no other reason than it really is old.
