Grand Canyon was formed in the year 2,345 B.C.E. by a sequence of five natural catastrophic events. The alternative theory presented in this work labeled "The Watts Theory" is supported by evidence and provides a thorough explanation for the formation of Grand Canyon. Testing a hypothesis to explain a landscape created by geomorphic processes in the absence of a human witness to record it is problematic. While inductive and deductive reasoning would be an appropriate approach to testing a scientific hypothesis, Watts Theory and theories derived from the conventional paradigm both employ an abductive reasoning method for drawing conclusions. Therefore, The Watts Theory is an equally acceptable explanation for the existence of the Grand Canyon. In the case of the Watts Theory, the body of evidence to draw from is more inclusive than evidence previously offered by theories that fall into the conventional paradigm. Therefore it is more probable than not, Grand Canyon was formed by a sequence of natural disasters occurring over a short span of time in recent geologic and human history. To be exact, 4,364 years ago. The author has included twenty-nine pieces of evidence about Yellowstone National Park to calm the fears of an eruption, simply put, Yellowstone cannot erupt. Yellowstone is not a Volcano, not even a super volcano. This theory is harmonious with historical biblical documentation. Here is a part that did not get in the book. As a first time author, positive response from qualified successful people was needed to continue. The first un-published copy was shown to a retired friend who was involved in building the SR-71. The SR-71 is the worlds fastest spy plane, reaching speeds excess of 2,200 miles per hour. To this day a faster jet has not been built. The SR-71 is on display in McMinnville, Oregon at the Evergreen Aviation & Space Museum. My friends response was "That Explains It". When I asked "Explains what" he said this theory explains Devils Tower. The next person I trusted for an answer was a friend who worked at NASA's Johnson Space Center in Houston, Texas. He worked on the International Space Station Computer Control Systems. I asked "If an astroid were to hit earth would it change gravity" His immediate response was "Absolutely". Further research led to the gravity change section in this publication. Research continued until there was a better pre-publication book. On a road trip to Arizona I stopped at the USGS office in Flagstaff, Arizona, where they monitor asteroids. https: //astrogeology.usgs.gov I had fear walking into the USGS and asking them to look over this new book about Yellowstone not being a volcano. They were so nice, there was an astrogeologist willing to look over the book. When asked what he thought about the book, he said, "You have things in this publication I have not heard yet" then he said, " I like it". This was enough confirmation from qualified sources to continue with years of research and write this publication about "How and When" Grand Canyon was formed.
