The great Flood of Noah's day was a time of unthinkable geological upheaval, such that "the world that then was, being overflowed with water, perished" (II Peter 3:6). No flood in human history has rivaled its destructive magnitude.

Few doctrines in Scripture are as clearly taught as the global nature of the Great Flood in Noah's day. Genesis clearly teaches that "the waters . . . increased greatly . . . and the mountains were covered" (Genesis 7:18-20).
