A global flood? Really? Many people want to dismiss this possibility as unhistorical or legendary. As we said in the previous article, the Sunday School type of illustrations of a cartoon ark help foster doubts about Noah’s Flood really happening. So is there any scientific evidence out there that supports Noah’s Flood?
When geologist J. Harlen Bretz proposed that a large flood was the explanation of the canyons and other features, his peers rejected and ridiculed his theory and wouldn’t accept it for about 40 years, believing that the canyons had to have been carved slowly in keeping with their uniformitarian bias. It wasn’t until the geological evidence forced them to accept a catastrophe that they changed their minds. (To read a complete account of “Bretz’s Outrageous Hypothesis” see The Missoula Flood Controversy [12] by meteorologist Michael Oard). Another article is Ice Age megafloods provide insight into Flood sedimentation Also see article: The Mystery of the Megaflood on whether the evidence supports one flood or many floods at this location.
Most scientists, whether they believe the Bible or not, acknowledge that most of the earth’s surface was once covered by water, the conventional scientists believing it was a sea that slowly advanced and retreated many times over millions of years, and the creation scientists believing that it was a global flood. One of the reasons for this belief is the fact that even on the highest mountains, such as Mount Everest, we find marine fossils! Most scientists believe that the mountains were pushed up and formed after being covered with water, but as I will discuss in later articles in this series, the rate and timing of the mountain uplift is interpreted differently. For an article explaining this in more detail, see this article by Dr. Snelling: High and Dry Sea Creatures

In Australia there is a giant sandstone bed called Ayers Rock or Uluru, which gives evidence of rapid, catastrophic formation. This formation is 18-20,000 feet thick, formed from sand grains of all different sizes (which indicates little time for separation of grain sizes) which have jagged corners (also indicating not enough time to be rounded off) and containing feldspar which disintegrates rapidly and so is not contained in most sandstones. The sand source is not local, but appears to have been eroded and transported from a source at least 60 miles away. All of these things indicate that Ayers Rock was formed by rapid transportation and deposition of sediment. The evidence points to this formation being deposited by a mixture of sediment and water called a turbidity current, traveling at a high rate of speed and depositing this formation in a matter of hours or days. {8}
