yes, science has proven that the original homo erectus came from africa, BUT science also proved that those that became homo sapiens (aka HUMAN) migrated north into europe.
yes there were off-shoots that despite being part of the superior-than-black group, they werent as high up as what became the caucasian race, and these spread out and became asians, and covered the middle ground

however, india and the middle east are sings that by one way or another – either desperate attempts by the black sub-species to imitate their superiors in migrating north, or possibly of those forcibly taken north by their superiors, but were unable to adapt to the colder climates of europe, and stayed in the hotter regions that in some small way compared to their african homeland.

the strongest of all were able to finish in scandanavia and not only survive but flourish, then in later times migrate back down in greater numbers to put a surge in the populations of east and west europe and lay the seeds of the human nations we have today,

the asian races, being capable of the hard work and unity like caucasians, were able to also develop strong nations and prove themselves to be powers to take note of

sadly, despite having only rudimentary abilities to exist, the black species survived out of simple cockroach stubbornness and even today, many millenia later, are still FAR behind any kind of realistic civilisation, with time having proven the black savages lack any form of imagination or creativity of their own, and have only developed due to contact with their superiors
