The Neolithic Revolution, also known as the Agriculture Revolution, was the time in human history when humans stopped being Nomads and started to settle in one place to establish the firsts civilizations, as was the case of the Sumerians, the oldest civilization on Earth.

They developed agriculture techniques, learned to benefit from the flood of the rivers to have fertile soil and grow crops, planted seeds, domesticated animals, produce a surplus of food, and established powerful city-states such as Nippur, Eridu, Lagash, Kish, Uruk, and Ur.

the first 10 amendments to the u.s. constitution are known as the bill of rights. those 10 amendments establish the most basic freedoms for americans including the rights to worship how they want, speak how they want, and assembly and peaceably protest their government how they want. the amendments have also been subject to much interpretation since their adoption, particularly the right to carry a gun under the second amendment.
