I was never fond of the theory that man hunted the mammoth to extinction.
This stuff is such hogwash, honestly, science is nothing but fairy tales these days, in search of either grants to futher their worthless careers or to carry the mantle of thier twisted ideology.
There are several things that we might want to absorb. First...”Comet Warming” destroyed a huge portion of life in North America...and basically formed the Mississippi River and probably over two hundred other rivers. Second...the vast amount of man in North America died, so Man version 2.0...basically came over AFTER 12,900. So we might have had several vast societies in existence. Third and final....we aren’t just talking about just a dozen or two dozen species of life that disappeared here....but we could be talking about a thousand different types of species that disappeared (so that the environmental guys don’t readily blame us for everything).
