As for the skull, testing for human DNA should be easy as there is plenty of material extant.
In which case I would like to see the peer review on how the writing on a stone can be dated with any accuracy.
I stand corrected, the writing, not the stone. the dating process, as I understand it, was done by those who date by looking at rain fall erosion. I should have added, this is not first hand information. We had a Pastor and his wife over for diner one night after he and she had spent a eyar in NM, and he was telling us about it, although he had not gone down and seen it himself.
