“They live in the African savannah, which is where humankind first evolved”

We have some evidence to suggest that early humans were there but it is a huge assumption and leap of faith to make a statement like this with certainty. This statement is more likely a religious statement than one a good scientist would make.

A good scientist would not make such a bold assumption without putting it in quotes or a star next to it. You cannot make this statement definitively.

As far as I was aware, this is established fact. Do you have any counter arguments that myself and the OP may have missed?

Do you believe it is in fact established? Science discovers new ‘facts’ all the time. To say definitively that humans first evolved here in the context of a 4 billion year old planet seems irresponsible at best.
