a)Science
All humans on this planet have evolved from human life that spawned from Africa...its science. I am human hence I am from Africa. (It isn't called the mother land for nothing)
b) I got the look
I was once asked by a bouncer if I "had some brother in me?" I replied "NO" in shock and awe that someone with my magnitude of whiteitude could be thought of as being "brother". But who knows, what if this-obviously-brilliant African-American man was just asking me what millions of other African-American people have wanted to ask me for YEARS???!!!
c) Facebook it.
I conducted some research on this idea and one of my venues of thought brought me to Zuckerberg's wild-world of Facebook. I searched my name and only three results came up me and...well you can check it out.
