Limes and sands have changed to rocks over the course of more time than the YEC models allow.

The universe is large and the speed of light is known and we quickly come to transit times that don’t fit the YEC timeline.

The Earth’s tectonic plates have moved very slowly as our modern oceanic crust developed.

We find large intrusive igneous bodies at the surface. It takes a long time for large buried igneous magma to cool. We find clasts of granite cooled and eroded out by the mid-Cretaceous period. This could not have happened during a 1-year flood

We find volcanos that developed through the geologic record at multiple times in non-marine settings, not the result of one catastrophic year.

Within the FG flood interval, we find many well-developed soils. Many show well developed root systems. Others show well developed caliche zones that tell us the climate was semiarid and stable for a period of time.

Columns from many YEC authors with radically different interpretations of the flood interval. If this truly was a single global catastrophe, why can’t the believers agree on where it is? I showed that their models tell us the rates of deposition that they demand and thus demand radically catastrophic processes, that are not observed.

Stromatolites are deposits, usually from tides that repeatedly covered and uncovered algal mats that trapped sediment. Some showed classic birdseye structures that result from exposure and drying of the mats for some periods of times. Stromatolites are found in essentially every age of rock that is interpreted as flood deposits.
