The white sands foot prints need more study. I think they are over 14000 years old. At 22000 years they would of been underwater. In 2022, skeptics noted that age estimates relied on carbon dating Ruppia cirrhosa seeds, whose parent plants can intake older carbon from groundwater, thereby potentially resulting in dates thousands of years too old. A study accounting for this effect suggesting that the maximum age of the footprints is likely only 15,500–13,500 in calibrated years Before Present, which is similar to the dates found for many other archaeological sites across the Americas.
