Noah's flood is a shadow of the flood that was responsible for plate tectonics. Lyell's uniformitarianism replaced the catastrophic theory. Darwin tried to adapt gradualism to his theory. That was popular until punctuated equilibrium was developed by Gould with Niles Eldredge. Still that does not change that a world flood could have caused Plate Tectonics. What is your theory for the mechanism if you reject the flood theory? Here is the story:
"All of a sudden, I saw the Father reach across space and break the water vapor shield and billions of gallons of water hit the earth. Wham! There went the one land mass, into many pieces, floating across the sea. Some of them overlapping upon each other and burying the dinosaurs between layers of earth. Some of the now new continents formed massive mountains, which at the same time caused deep valleys to form. The water kept coming, until all the earth was completely covered. Then God leaned forward again and blew onto the earth; immediately ice began to form over the surface of the waters and life stopped as the earth, covered in darkness, entered into the Ice Age!
The scene changed (millions of years later as the earth lie dormant under the ice) and I saw streaks of light come from Heaven and the Spirit of God was hovering over the frozen planet, waiting. Then I saw God lean forward and He blew upon the ice and instantly the earth was defrosted. Once again water covered the whole earth (Gen 1:2) and there was no land mass visible to the eye.
God spoke again and light was! It was so fantastic, as I watched God re-create the earth, different atmosphere, animals and even man, but eventually they sent me back down to earth. If you accept Christ and make it to Heaven; you can go to Creation Lab and see this too." Kat Kerr
