Answer:
According to some new archaeological reports, the Pre-Pottery Neolithic were the first in the civilised world to develop a systematic large-scale food storage system. A site near the Dead Sea in Jordan reveals evidence that shows that this civilization had a sophisticated food storage system. The strongest evidence of food storage can be retrived from Ain Mallaha, here pits were formed but the use of the same is still a mystery. But it could possibly be for food storage.
