At best, all that can be said is that there was a low oxygen fire event at Cerro de Capivara about 100,000 ago.As to the refutation of the Clovis First Theory, that has been well established for over 20 years.The findings suggest that humans left Africa much earlier than originally believed.

“We need to go back to where modern humans emerged in east Africa. The period between 200,000 years ago until 130,000 years ago corresponds to a time when there was a global ice age.

During ice ages, global sea levels fall as water becomes locked up in the vast ice sheets in the northern and southern hemispheres.

The evidence that fire existed in Brazil 65 thousand years ago is an indication that man was at the site at least 65,000 years ago, since researchers found charcoal, which is the result of fire making. Niede Guidon supports her dating of a human population in Brazil 100,000 years ago to ancient fire and tool making. Guidon, who conducted excavations at the site, notes at the site is 100,000 years old.

At in the video scientists proved that the tools are the result of human craftsmanship.

The archaeological evidence from the Americas and Eurasia make it clear that people left Africa 100 thousand years ago to settle other parts of the world.

This indicates that although there is firm archaeological evidence man began to settle Western Eurasia and other parts of the world 60 thousand years ago, during the interglacial period between 130-100 thousand years ago mankind probably made its first Oo A exit. Choi, (2011) Ancient Arabian Artifacts May Rewrite 'Out of Africa' Story, T. Evolution at the Crossroads: Modern Human Emergence in Western Asia, American Anthropologist,102(1).It appears that the first Oo A exit was to Arabia, where archaeologists have found tools dating back 125,000 years.Paleontologist Tony Marks claimed these tools came from Africa in an interview by Wilkins. In east Africa, however, there were contemporaneous Paleolithic assemblages that not only used bifacial techniques to make some of their tools, but also used the other two techniques, blade production and radial (levaloir).Charcoal is recognized as a reliable indicator of human habitation. Peter Veth of the University of western Australia, in a recent article published in the Quaternary Science Reviews, used charcoal, dated by ANSTO's Centre for Accelerator Science for Aboriginal settlement at Barrow island between 46.2ky and 51.1kya.

The simple presence of charcoal in and of itself is NOT proof of human activity.This illustrates that charcoal can be a reliable artifact to denote ancient settlements. Without proper archaeological context like a hearth, wind break or evidence of butchered bone, it is just charcoal.This means that AMH were in China by 100 thousand years ago, like the people at Qafzeh caves found in Israel and in southern Crete.
