My understanding is that the rainforest as we know it exists where it does in part because humans spent such effort cultivating edible plants in the area. Many of the most edible crops are not native to the regions in which they now grow, there's not much evidence of ancient-grown forest before ~5kya, and there's good evidence of burn-based plant and soil management.
