I figured the distance between Europe and North America to be currently roughly 3000 miles, and for that distance to have been traveled in a rough 4500 years would mean moving at an average rate of 1000 miles in 1500 years, or 10 miles in 15 years or 3/4 mile in one year, or 3960 feet or 47,520 inches, or 11 feet per day. I put that number at the midpoint of the time between the Flood and today, or roughly around 100 BC or so. I figure that's the speed at which the continents would have been separating in 100 BC. Before that they were separating at a faster rate that increases back to the beginning, and since then at a slower rate that decreases to the present rate of 2-4 inches per year.
And this behavior has no explanation at all and on top of that, somehow, magically, if we take the
current rates of movement and the measurements of the ages of the rocks formed during that movement we come up with just the distances traveled. Which has the marvelously simple explanation of them moving at that measured current rate for the time measured.
Yet, another astonishing coincidence that you can't explain.
