I do love a good jape from time to time, but colonization is when you show up and expel/enslave/imprison the people who are already there, which is decidedly not how the spread of people from Africa worked
That's literally not what colonization means. I also promise that most human history is bloody even if you don't know about it. Humans spread out from Africa across the world. My slightly related to me ancestors conquered subjugated and killed their slightly related ancestors. We're all one race.
