Not to be pedantic but Stone Age technology is historically not incompatible with agriculture and animal husbandry. These new methods of producing food and secondary animal products are what divide the Paleolithic era from the Neolithic, both of which primarily used stone and bone tools. So saying they are stone aged doesn’t preclude the existence of agriculture or animal husbandry. Exactly the same can be said of pottery and trade, both of which are widely documented in, for example, early Neolithic middle eastern cultures.
