They paid this guy, who makes replicas for the tourist. To claim he carved all of them. Question:
If no man has ever seen a dinosaur, how did this man know the exact designs on the skin that would be found after all this was done? Chance? No, he saw the original ones so he knew exactly what to draw.
The thing that the atheist leave out is how strict the laws are about having any Peru artifacts. They will arrest you, you'll get sentenced to 5-10 years in prison. And because the prisons are so bad, most only live 3 years because they starve to death or catch a disease.
So why would this man admit to ever owning an original Inca stone when it would mean certain death? They don;t tell you that in the BBC documentary. Because they are not used to telling the truth.
