In this comprehensive treatment of the ongoing conflict between creationists and evolutionary scientists, well-known geomorphologist Arthur Strahler carefully examines creationists' claims of scientific evidence for the six-day divine creation of the universe, followed by the catastrophic flood of Noah, as claimed in Genesis. The creationists' arguments are examined and evaluated against the findings of mainstream science in the fields of cosmology, astronomy, geophysics, geology, paleontology, and evolutionary biology.
