I donāt know of any creationist who thinks that, and it now seems clear that @Roy misspoke, meaning to say that everything above the Precambrian is a flood deposit. Thatās probably a minority opinion, but at least there really are people who hold it. There is no standard YEC stance, but if thereās a plurality opinion itās that the Paleozoic and Mesozoic are flood deposits while the Cenozoic is post-flood. Thatās the position of the most āscientificā of the YECs, like Kurt Wise.
My bad, I read it as flood deposit, not post-flood deposit. My brain couldnāt contemplate such an absurd suggestion so it must have tried to correct it somewhat.
No, I definitely meant everything above the Precambrian is seen as a post-flood deposit.
Thereās a description of the recolonisation theory at this site - it was hard to find, because itās only promoted by a small group of creationists and rejected by the majority.
2. Cambrian.
Many have mentioned āthe Cambrian explosion,ā this is because complicated and often advanced marine life forms are suddenly found here, indeed almost all phyla is here. Evolutionists are very embarrassed about the Cambrian strata for very obvious reasons. This represents the recomposition of shallow seas following the Flood. As water was draining off the land following the Flood, huge sediment deposits were being produced - absolutely ideal for the production of fossils! For Dr Surtees, this period is clearly post-Flood.

I note that one of the sources puts the end of the flood within the Cambrian and another at the end of the Carboniferous. Even the recolonizers canāt agree on their hypotheses.
