For more than a thousand years after the death and resurrection of Jesus Christ it was assumed that a great deluge of water destroyed almost all life on Earth. The story in the Bible of a destructive punishment against a violent people, with only a handful of survivors, was looked on as part of history. Noah and his family were considered real people who built a real boat and safely rested on the top of a Mountain top. The children of this great prophet who believed to have had children and repopulated the world with people and animals. Religious believers looked around at the world around them and saw evidence in the rocks and the landscape. They would point to massive boulders, for instance, and explain that only a great rush of water could move them to where they now rested. No one at first questioned these conclusions.
Religious investigators continued to study geology with the hope of understanding the Great Flood until the mid-19th Century a new concept became popular. A number of influential researchers developed the theory of uniformity. They believed that whatever happened in the past can only be understood by applying modern observations. In order for geological evidence to make sense the processes of nature must have taken many millions of years at a very slow pace. From this came the key to the theory of Evolution and the rejection of any worldwide deluge evidence. The very idea of a violent catastrophe that changed the Earth’s history was unacceptable. Changes in the Earth and its life was slow, gradual, and easy to observe.
A generation later the idea of uniformity is still accepted, but with very abrupt disruptions. Modern geologists talk of at least five extinctions that can only happen because of major catastrophes. Some even argue that humans themselves are causing a sixth extinction, although with varied theories on when it will be fully realized. The most famous life destroying catastrophe is a meteor that destroyed the dinosaurs. Like all theories it was at first rejected, but eventually enough evidence was found to be accepted by most scientists. There is even a crater off the coast of Mexico that is considered the exact place the celestial object hit that did the damage. A geological layer of clay containing high levels of the metal iridium is believed to represent the exact time of impact. Even the Great Flood is, to a degree, getting a second look.
