"Evolutionists think creationists have little or no evidence in support of the worldwide Flood revealed in Genesis. However, they refuse to acknowledge the possibility that it is the Flood's results seen in the vast geological structures all around them. Ever since Scottish geologist James Hutton (1726-1797) and English attorney Charles Lyell (1797-1875) popularized the concept of uniformitarianism, uniformitarian geologists have believed that the geologic record can be explained by present geological processes and rates. Recently, more and more geologists admit that major parts of the geologic record are the result of immense catastrophic floods, occurring intermittently over long periods of time. They have postulated a world-inundating tidal wave caused by an asteroid impact as an explanation for the extinction of dinosaurs. The Bible, however, tells us that they perished in the Flood. We assume their survivors from Noah's ark did not flourish well in the post-Flood climate and became extinct along with a growing number of other animals.
When Immanuel Velikovsky wrote Worlds in Collision (1950), and Earth in Upheaval (1955), he went against the conventional uniformitarian wisdom of the day. Although he was not a creationist, he believed strongly that our solar system and our planet were shaped by cataclysmic events.
Two German evolutionary geologists, Werner Tollmann and Edith Tollman, defended their belief that there was a mountain-covering world flood about 10,000 years ago. According to them, a massive comet broke into seven pieces and slammed into the world's oceans. [Tollman] The Tollman's have already identified five marine impact craters and are looking for two more because some ancient flood accounts (non-Biblical) mention seven glowing objects in the sky. The creationist family magazine, Creation ex nihilo, had an article on this (16:1, pp. 46-47)."
