https://answersingenesis.org/geology/grand-canyon-facts/fossil-evidence-grand-canyon/ This will be the beginning of a string of discussions we will have concerning whether or not young earth claims stand up to scrutiny. Some excerpts: Flood geologists can simply accept the directly observable evidence for rapid, continuous deposition, the more scientific choice at this point. There’s further evidence to encourage Flood geologists to think that they have made the correct scientific choice. If individual sediment layers were hardened, uplifted, eroded, then covered again with water, it’s likely that the lower hardened layers would crack in a pattern diﬀerent from cracks formed in layers above them, and produced and moved millions of years later. In other words, there should be “buried faults,” cracks through one layer not continuing into the layer above, but there are virtually no buried faults above the Precambrian in the Grand Canyon. There are faults, all right, but they cut continuously through the whole sequence of Paleozoic layers present (Cambrian, Mississippian, Pennsylvanian, and Permian), not just part of it. That evidence suggests the whole “layer cake” was formed rapidly and continuously, without a major break in time—just as you would expect from understanding the Grand Canyon in terms of what the Bible says about Noah’s flood. What do you think?
