"Same weapons" does not mean anything.

They didn't have the same weapons. Europeans have always been ahead of Subsaharan africans. In the mesolithic, Europeans had already domesticated the dog and created harpoons. And many other things. And he is being disingenous when he talks about "farming and agriculture" because the beginning of the neolithic is defined by when areas start farming... And different areas enter the neolithic during different times.

It is so bad actually that while "Neolithic" is defined as "When did Farming start in this area", in Africa they had to invent a new term entirely called "The Pastoral Neolithic refers to a period in Africa's prehistory marking the beginning of food production on the continent following the Later Stone Age. In contrast to the Neolithic in other parts of the world, which saw the development of farming societies, the first form of African food production was mobile pastoralism,[29][30] or ways of life centered on the herding and management of livestock."
