The Creation of Bronze items led to a rapid expansion of farming and military possibilities. Bronze was effectively the deciding factor in military and state affairs if you had Bronze, you were someone to be feared and respected. To quote the book " It was expensive to make and expensive to distribute to soldiers" (Western civilization, volume 1 Chapter 3).  Bronze was effectively a king maker.  The creation of Bronze caused a massive surge of trade routes and inter empire diplomacy.     It should be noted after the collapse of the Bronze age, The Iron age really took off and began the technological revolution

The Creation of Languages was the biggest milestone in human history as it allowed for communication with others and cooperation between peoples. Cuneiform was the first language created and was used to relay information. It was mainly used in Sumerian  languages, but the language evolved from Cuneiform and transcribing things on clay or stone tablets began to be used as a way of storing or transporting information. I am pretty sure this is where the saying "Etched in stone comes from".    to quote the book "Each state, large and small, oversaw diplomatic exchanges written in Akkadian..." (Western civilizations, volume 1 chapter 3).

The creation of pottery was probably the third largest achievement in history. With the creation of potter, namely vases and urns we are able to store goods for longer periods of time.  Pottery is also a form of art with it namely being used by the Greeks. The main types of styles depicted on an urn are red figures and black figures. The colors on urn  they were changed by the amount of heat put on the clay and their pigments.  Pottery was used to store water, herbs, spices valuables and sacrifices for the gods.   Potter could have also been used for story    telling though this is a guess on my part.

Trade as the life blood of any major city or empire. The giving of goods and services was important as other cities, even nations had something someone else wanted and were willing to pay for it.  Bronze as previously discussed was expensive to make and to arm soldiers. The introduction of bronze had business booming, but the introduction of Iron was a new idea that changed everything.  Food and grain were extremely important as it allowed for countries suffering to still be able to eat and  the merchants made a killing. Though They were also the targets of bandits. Merchants also made up a large part of the  nobility, but were probably second to the priests.

Agriculture was the first step towards civilization.  It was what allowed cities to prosper and   allowed for the creation of modern society. the first humans were nomadic but upon realizing that they could grow food where they stayed for long periods of time, they began to form hierarchies, but some left wishing to avoid this, hence the creation of diverse cultures.  The most notable form of agriculture is the Egyptians using the Nile for farming. the Nile periodically flooded, and the soil was extremely fertile, and the Egyptians learned to time this and use it to their advantage.   The Nile was also known as the giver and taker of life as when it flooded it often took the lives of many, and the occasional crocodile being washed ashore. Without agriculture, we would not be able to live as we do now. To quote the book  "Wood also placed a large role in everyday construction" (Rust, 14.1). This is important as many Areas did not have access to trees so often time they wood would be used for important structures like temples and palaces.
