So ships with animals, arts, technology being sent to China right before Euro came to Africa.... and more recent Nigerians trading mid east technology and culture.... allows you to conclude that knowledge in Africa was lost over the years.
I'm done if your premise is that Africans had all these technologies and then lost it all in the window that Euro came in.... I wouldn't imagine that's what u actually believe.
nigerians did not exist 500 years ago, nigeria is a european creation that became independent in the 50's
for the life of me i have no idea what china has to do with anything
