Mesopotamia was home to some of the oldest major ancient civilizations, including the Sumerians, Akkadians, Persians, Babylonians and Assyrians. Mesopotamia housed some of the world's most ancient states with highly developed social complexity. Mesopotamian people developed many technologies, among them metalworking, glassmaking, textile weaving, food control, and water storage and irrigation. They were also one of the first Bronze age people in the world. Early on they used copper, bronze and gold, and later they used iron. Palaces were decorated with hundreds of kilograms of these very expensive metals. Also, copper, bronze, and iron were used for armor as well as for different weapons such as swords, daggers, spears, and maces.

But, to a scientist they might answer something like “nitrogen-rich polymeric sheets”, because precisely defining the chemistry of a material is important to them. Or at least, that’s what they called a type of organic material found in the sample collected of the asteroid Bennu by the OSIRIS-REx spacecraft. But more informally, scientists have taken to calling it “space gum”, and the process it formed under is making some of them question current models of asteroid formation.
