Answer:
It really depends on your definition of government. Not very helpful I know...
Explanation:
I doubt that it is 3. Although it is possible. If a government is a body that passes laws then it is most probably 2, a monarchy. The first monarchy originated in about 400 BC. Before that, humans just worked for whoever owned the farms. Tribal rule is also possible as humans did create tribes to hunt and gather and it is likely they had a leader or "alpha-male". Anyway, good luck with answering that question without getting into some serious semantics.
