None of this is true. We can see evidence of the gradual spread of the oceans over time in a multitude of ways.
Incidentally while the movement is often slow and regular most of the real changes to earth's landscape occurs in sudden fits and starts. The very nature of reality is a matter of repeating cycles and processes that express themselves suddenly but where life all change is sudden with things like plate tectonics or orbits most changes will tend to be gradual for protracted periods of time until there are sudden changes that are frequently violent. There's a lot going on in these "gradual" periods that are not apparent. There's are no gradual periods with life on any level and virtually all change in all life occurs in a very very brief period of time. I have an idea right now to go do something else so I'll dot this sentence and click "post reply".
Guess what -- it's those "sudden changes" that are the primary reason for what people call "punctuated evolution." A sudden change in habitat (an earth-quake raises a hill, or re-routes a river) makes habitat changes that must be responded to by those living in the habitat.
There is another reason, though, too -- unlike what happens geologically, which lays down much quite permanent evidence -- fossilization is in fact extremely rare, requiring very special circumstances. That needs consideration as well.
So you see, I can get where you're going, while still accepting the FACT of evolution.
