Lots of people seem to think 'we' (the academe) know all there is to know. They claim science has killed off tradition, and we are highly enlightened by comparison to our ancestors.
The problem with their ideas is that science and history do not agree! Prehistory, once the realm beyond 8000bc has now been stretched to at least 12,000 BC.
Enjoy and be amazed at the wisdom and beauty of our most ancient ancestors...so far!
