Answer 1

for they were herders wondering most of their life and white people never knew the definition of their clans or religion for people now as for now are define by belief but some want to call it culture . so their skins were burned by the different climate and the dust was heave in those days so in an most explanation people from Europe just named the people as they see them until they heard from us telling the who we are taken from the first of our kind that was Xhosa actually name of our fore father Mr Xhosa we were his children.
