Before we examine the “grandest of canyons”—and the greatest geological laboratory on Earth—we should reflect on how the “Two Faulty ‘Principles’ ” described on page 210 produced centuries of confusion within the Earth sciences. Without understanding the powerful events of the flood that produced flutter and liquefaction, one had to assume (1) that the slow, relatively uniform events we see today operated throughout Earth’s history (uniformitarianism), and (2) that each sedimentary layer and its fossils were laid down sequentially worldwide over billions of years (superposition). Therefore, without understanding that layers and fossils were rapidly sorted by liquefaction during the flood, people had to assume that billions of years were needed for a “magically produced” single cell to somehow develop into all plants and animals (evolutionism). Correcting these errors, now ingrained in the world’s social fabric, will require a willingness by many to study, educate others, and follow the evidence wherever it leads.
