Perhaps the fact that the continents all fit together, even along the pacific ocean, but only on a much smaller planet, and that there is no evidence of tectonic plate subduction. As the earth expanded, cracks formed in the earth's crust. These weak areas where the earth has cracks allowed mantle material to rise to the surface, filling those cracks. As the cracks widened, the oceans basins were formed. None of these ocean basins existed prior to 200 million years ago, and probably more recent than that, assuming that I am correct, and dating methods are flawed, all of the earths continental land masses were all interconnected. That could have only occurred on a much smaller planet, and that planet existed less than 200 million years ago.
We have extensive evidence of sea life from before 200 million years ago. ALL of the paleozoic was before that time. Every trilobite was before then, for example.
Sorry, your imagination doesn't fit the evidence.
