Floridian Supremacy Reply to @DrGregLittle2: Some 18,000 years ago, sea levels were likely some 400 feet lower, essentially meaning Florida, Alabama, Louisiana, and other states along all the US had some shorelines over a hundred miles out from today's coasts in some areas. Florida, for example, was twice as large then. Whatever evidence that still exists of the oldest sites in the Americas likely lies buried under sand and silt in the submerged areas. There is ongoing research in this area.
