It just shows you that all that "earth is 4.5 billion years old and humans existed only the last 200,000 years" is total crap. First of all, the dates are all wrong (there is no 300 million years old rock on earth, because the whole universe is only about 6000 years old), and second, it shows you that humans existed throughout the entire existence of earth (all 6000 years), not just a tiny portion of it.
Aside from that, Siberian hillbillies are the most trustworthy source of information, so this news is real, not some sensational invention.
