Final answer:
The population of the village of Ali Kosh is not provided in the given information. Historical demographics rely on various sources to estimate population sizes, which could vary widely depending on the time and location of the settlement. Exact figures require specific references to the village in question.
Step-by-step explanation:
The village of Ali Kosh contained only about a specific number of people at any one time; however, the given information does not include an exact number for this particular village. From the provided context of various historical populations, it can be inferred that villages and small towns during different periods could have populations ranging widely, such as the mentioned early Mesopotamian cities having between 50 and 100 million people on Earth or a village like Minuf al-'Ulya with 20,000 to 40,000 prior to depopulation events. Yet, without a direct reference to Ali Kosh, one cannot provide a specific population figure. This assessment of population sizes concerns the field of historical demographics, which often relies on archaeological findings and historical documentation to estimate the sizes of ancient settlements.
