The details of the Flood have profound implications for explaining the geology of the earth today. In the 1960s secular geologists discovered a broad pattern in the rock layers that has puzzled them, but the Bible holds the key.
The bathtub Arks and “forty days of rain” we often hear in Sunday school don’t begin to do the Flood justice. The forces that God unleashed tore apart the entire world, destroying all land-dwelling animals in a complex sequence of events that is hard to imagine.
No other catastrophe has ravaged the earth on this scale, so we have little to compare it to. For that reason it’s all the more important to interpret the Bible’s chronology of events correctly if we hope to understand the complex geology that the Flood produced and we observe today.
Some people interpret Genesis to mean that heavy rains caused the sea level to rise steadily for 150 days, and then drop steadily until the end of the Flood, on day 371. But a closer look at the Bible indicates that another sequence is more likely—the waters peaked on day 40, and then rose and fell until the end.
This sequence of events could help solve one of the greatest mysteries in geology, megasequences (described below), which has long puzzled geologists, both evolutionists and creationists.
