Europeans would show up and my Native American homies would be armed with cartridge rifles, six shooters and a crank rotary machine gun.
I would try for better, but I think there just wouldn't be the time for fine tooling more advanced fire arms would require. Even getting all that going before I croak is going to take a lot of ambition.
Also assuming they don't think I am some evil spirit that they quickly kill when I demand industrial metal facilities be constructed.
Oh, they would probably also have penicillin before the white man, so that would be a major advantage.
If your argument is that humans can only be "native" to southeast Africa... that's dumb. It might be defensible in an ecological sense but sociologically the word is used differently.
