“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.

My understanding is that the known fossil record is extremely clear on this, and is additionally quite consistent to the extent where I'm unaware of any competing hypotheses that are taken seriously.

As far as science goes, it seems to be as established as it gets. Again, unless you've got convincing evidence to the contrary. Really not sure what your agenda is here?

[fjabre]

Plenty of competing theories on the origins of humanity on a 4 billion year old planet some in which the origins of life came from elsewhere in the universe.

I think this may be the most recent evidence that modern science has discovered.

Perhaps you mean to say we wont dig up any fossils that say otherwise and that the case is closed?

As if the entirety of the fossil record on earth has been exhausted and we have nothing more to discover.

My agenda is to make sure we are being good scientists and not religious about our findings.

Religion is not science. It is a belief.
