Actually it is because you are wrong.
I can't accept your definition of Art because it fails to acknowledge important theoretical and practical aspects embedded in a lot of old styles. In such styles, the healing informs the fighting, and vice versa. If you disagree, it's not because I'm wrong...
1)I never said simply coming form Africa makes it magically old
Being in Africa does not magically translate into a lineage handed down from Olduvai Gorge Homo Erectus, the Pyramids or what have you.It's a fair cop that Africans have tinkered with, lost, found, rediscovered, and told dodgy stories about their MA lineages as much as anybody else.
