Many evolutionists regard the Bible as myth and allegory. Strange that after all these years, scientists who rejected catastrophe and embraced uniformitarian geology, sometimes for no better reason than to deny the Bible, are now embracing a catastrophic scenario to explain geology and evolution. This is strange because creationism teaches that the world's geological features and species diversification happened in a few thousand years. The difference is evolutionists believe these things took place in sudden spurts, each separated by millions of years. Creationists speculate that the Flood produced the fossil segregation patterns, e.g., trilobites in the Cambrian, dinosaurs in the Jurassic, etc.
Evolutionists note five major periods of mass extinction in the fossil record.
Raup refers to these periods as mass killings. This initiated rapid, runaway subduction of the oceanic crust deep into the mantle, and upwelling of melted mantle which filled the ocean basins with hot magma and created unimaginable quantities of steam. The displaced ocean waters swept over the continents and deposited marine sediments on all the continents. There are more marine sediments on the land than land sediments. The five mass killings are the result of major depositions from transported biomes driven by plate tectonism during the Flood.
