Secular geologists hypothesize five major mass extinctions in Earth history and maintain the most catastrophic of these happened nearly 252 million years ago. This Permian extinction, or Great Dying, supposedly resulted in the loss of 70 percent of land species and 95 percent of marine species. What really happened?

Can we know what the pre-Flood world looked like? How has Dr. Clarey’s cutting-edge megasequence research improved our understanding of the Genesis Flood? Uncover clues to Earth’s catastrophic past in this geological survey.
