"I’m glad that they’re all proven wrong now."

Where exactly did you see that proof?

"The new study points to a different process for much of the assemblage." "The match offers an explanation for why the fragments appear so widely scattered."

This is the language in use here. We are talking about bones that were buried 12 000 years ago, got chewed partially by rodents, crushed by earth pressure and moved around with the soil. So no indication that there was human sacrifice, but also no definite proof otherwise.
