Many Christians are reluctant to accept the Bible’s clear teaching of a recent creation because they believe secular dating methods prove that the earth is extremely old.Because of their belief that “the present is the key to the past,” however, secular scientists ignore these clues and assume that seafloor sediments have always been deposited very slowly.The Milankovitch Ice Age Hypothesis Secular scientists use the Milankovitch (or astronomical) ice age hypothesis to assign ages to seafloor sediments.If one plots these values on a graph, many “wiggles” are apparent at different depths within a sediment core (Figure 3).Within the seafloor sediments, very high δO values are thought to indicate the times at which Earth had the greatest amount of ice.
