ok, keep going, you're almost there: if you follow that back to the Olduvai gorge,, like you say, to the earliest humans - where were those hominids who were enslaving each other? come on, you can do it....

were they white people?

This idiotic statement:

Much people forget before black slavery there was white slavery… So its just good if there is none slavery.

Much people forget basic grammar too, apparently.

No, there's always some idiot who has to bring up that some white people (maybe even their ancestors) were also slaves, so he shouldn't have to XYZ. Or that people of color might have ancestors who enslaved each other, so XYZ. It's all silly bullshit.
