How long ago did the flood of Noah occur?
...The fossils date back about 68,000 years to a time when central Texas had fewer trees and more grassland.
A condition which still exists for much of Texas. According to secular scientists, there were still mammoths and ground sloths running around North America as recently as 10 or 11,000 years ago. The evidence here is not inconsistent with the animals having been overwhelmed by a flood, so the only question is dating.
