(That is, do creationists deny >>the possibility of continental drift, or do they not accept the >>allowability of enough geologic time for continental drift to occur?) "Continental drift" is more properly called "plate tectonics," since it is the plates, rather than the continents, that move (the continental crust rides along on the plates). Plate tectonics is as well established as any scientific theory, e.g., that the Earth orbits the Sun (or the theory of evolution, for that matter): the evidence that the plates have moved and are moving is overwhelming. Almost every earth scientist in the world now believe that all geological and geophysical phenomenon are explainable in terms of plate tectonics, or at least are consistent with it - the exception is the Soviet Union, where V. V. Beloussov, the Chairman of the Soviet Geophysical Committee, has personally squelched interest in geodynamics (but that's another story that I'll tell if anyone is interested). The rare observational data which does not fit the present rather crude model is being vigorously studied, and is being used to refine the model. There is very convincing evidence that the present cycle of plate motion begain about 250 million years ago, and that this cycle was preceded by other cycles all the way back into the Precambrian. If this conflicts with creationist notions, so much the worse for the creationists. Incidentally, plate tectonics also beautifully explains the available paleontological data on dispersal of species.
