The waters rose and increased greatly on the earth, and the ark floated on the surface of the water. They rose greatly on the earth, and all the high mountains under the entire heavens were covered. The waters rose and covered the mountains to a depth of more than twenty feet. Genesis 7:17–20.

This was a period of great sedimentation on the earth, especially on the parts of the crust that now form the present continents.

Once the waters of the Flood had completely inundated every piece of land on the earth, they began to recede, and they continued to recede for a period of about seven months, until the continents were dry. Where did the waters go? They flowed into the ocean basins which were widening at the time, or deepening, or both.

Geologists actually catch hints of this event but their interpretive framework, especially the dates they have assigned, prevents them from making the connection. For example, they speak of a time when the Indian and Atlantic Oceans were ‘born’—of the break-up of Gondwana….
