There are some creationists who seem to view the break up of Pangaea as happening at the time of The Flood, it also seems there are some that believe it happened after The Flood. You are a creationist, I am asking you which you believe. I would like to sort these ideas regardless of whether I agree with the scientific reasoning behind them or not with a larger macro view of how it fits together. I want to see how the puzzle looks from at least one yec point of view.
You seem rather focused on the individual instances involved in each point of view. Discussing the science is certainly one way to get lost in the details. And answering generally that you view the events as a product of catastrophism does little to fully detail and answer. I would expect many points I can plug in myself with research as views are not really going to deviate too much. Obviously, you would have to believe that man and dinosaurs roamed the earth together. Obviously you would think that the grand Canyon was formed quickly, but when did the dinosaurs go extinct, when did the grand Canyon finish or forming, when did the wheel get invented? Surely catastrophism can answer some but not all of the events that I want to plug into this timeline. So while you have in a roundabout way answered some of the questions presented to you, some still sit unanswered.
Before we get to Pangaea, I like you to at least "recognize" that uniformitarianism has acted like a bully since it seized power in the 1800s. It is the driving force of evolution today and does not recognize catastrophism unless it helps promote evolution. The atheist scientists have stolen ideas and theories presented by creation scientists. In other words, catastrophism is a valid theory using science. Otherwise, what I say will not lead you to think that the creation timeline is valid. Where Christianity and creationism comes in is that it supports catastrophism and not uniformitarianism. There is nothing in creation that took a million or billion years to form.
Now to Pangaea. I believe in a supercontinent. The evidence seems to fit that the continents broke apart as theorized by continental drift theory. Look at North and South America coastlines and Europe and Africa lines. The Bible does not disagree with it. For example, Genesis 1:9-10 states: “Then God said, ‘Let the waters under the heavens be gathered together into one place, and let the dry land appear;’ and it was so. And God called the dry land Earth, and the gathering together of the waters He called Seas.” The fundamental difference with evolutionists is how long it took to separate. The continents are still drifting apart slowly so evos using uniformitarian thinking assume that is the way it was in the past. GPS can tell us in inches how much they move.
However, we had undersea earthquakes and the continents separated and more water came up to cover the earth. Evos state that it started with a very enormous volcano. They love volcanoes as their grand cause. (I love volcanoes because they make money for me which I will keep secret.) Anyway, the geological evidence backs continental drift. Regarding the continental drift theory, the evos stole the theory of plate tectonics. They didn't believe Alfred Wegener back in the day, but now use his theory to explain why the continents are "slow-w-w-w-ly" drifting apart. To answer your question, it is theorized by creation scientists that Pangaea separated into today's continents and oceans during Noah's Flood.
