As previously noted - it would be practically impossible to find our earliest ancestors.
Mankind has been travelling around the world for thousands of years trading goods, knowledge and slaves ; whether that's slaves from Europe to the south or from the south to Europe in the north.
My school history included a short lesson on Alexander the Great of Macedonia and a few decades later whilst in the Netherlands I heard about him again as giving the name to a small town down the road. He and his entourage would regularly travel along the Spice Road/Silk Road and he would apologise for his late arrival at a country hostelry saying "It is Late" - and that's how the town got its name of "Sittard".
