Yes, I suppose I should clarify that.
What I meant was that this idea that the oceans were where the ground was pushed down, and the continents were then left high and dry, does not correlate with geological evidence of continental drift, plate tectonics, and the like. The reason that the continents are higher than the oceans is that basically, the continental crust is of a lower density than the oceanic crust, and the mantle is a higher density than either. So, both of them "float" at different levels in the mantle. So, it is not that the water is "pushing down" on parts of the earth and forming mountains. Mountains are often formed when seismic plates interact and colide, or subduct. The ocean does not affect this, and the process is much too slow to be accounted for by a 40 day period.
