The convolutions necessary to reconcile plate tectonics with a WORLDWIDE flood, all within the last 6000 years, alone are mind-boggling.
The fossil strata I have explored in cliffs up at 10k feet in the high desert in New Mexico were sea fossils, and they were not the result of flood deposit 6000 years ago.
In 2007 I was elk hunting in the Schell Creek Range in eastern NV at around 9,000 feet. My partner and I ran onto a boulder encrusted with fossilized shells and trilobites.
