Hooberus there is a logical error in the cited work you have provided. The author of the article says that the methodology used to date the site by scientists is flawed. He relates that since radio carbon dating was not used the accepted age of the site is incorrect. He has missed the mark , he obviously does not understand how radiocarbon dating works.

2 Radiocarbon dating needs the specimen to be a carbon based. biological specimen.
Where in the article does he discuss carbon dating?
