“Eventually” sounds like conjecture more than fact. Any empirical data to support that position?
The ones that have been developed by scientists to place approximate ages on things such as superposition, stratigraphy, certain mineral isotopes, fossil records, uniformity etc. Not sure if that is what you meant; I certainly did not do the dating, but I have been in this area and seen the spectacular results of time and erosion. My favorite part of the country with its whimsical rock formations and stunning vistas. You can’t help but think God was in a playful mood when he created it.
