You, uh . . . you really take this sort of thing seriously don't you? This sort of thing always incites me to question. How do they come to that conclusion? How do they date this sort of thing? No other civilizations existed simultaneously with the Mesopotamian Civilization's origin? What constitutes a civilization?
Take . . . England for example. Is that a civilization? When did it start? How long did it exist before qualifying as a civilization? Is it still a civilization?
Civilizations as listed and described in sooda’s quoted article, points to periods of urbanization, hence city-states, cities, towns, where population shifted from rural villages and rural cultures to that of urban sites, such as towns and cities.
Urbanization and civilization required even greater cooperation than that of village-leveled farming cultures (Neolithic cultures and industries) or the older hunters-and-gatherers cultures (Palaeolithic cultures and industries).
Another factor in civilisation is trade. Objects made, goods, such as pottery, were often exported and imported, give indication of the levels of civilisation.
What you need to understand that human culture have longer history before civilization “happened”, so they predated metallurgy industry and predated writings.
And since writings didn’t exist in Neolithic period (10,000 - 4000 BCE), and they were scarce in the Chalcolithic period (4000 - 3150 BCE), writings became more abundant in the Bronze Age, and even more so Iron Age, they are more often than not, not writing history. Which is why archaeology is so important, when it come to learning about history before writings.
Example of the earliest writings were discovered in Uruk, which you may know as Erech (Genesis 10), as one of the cities SUPPOSEDLY BUILT by mythological Nimrod. It was archaic form of cuneiform, pre-Sumerian cuneiform; the inscriptions were found at one of the Uruk IV temples (c 3400 - c 3300 BCE).
Uruk have far longer history than the Bible (Genesis 10) give credits for, and predated the Bronze Age (which started in the Jemdet Nasr period, 3150 - 2900 BCE) by at least 2000 years. The earliest level or strata of Uruk (Uruk XVIII) was dated to around 5000 BCE, known as the Eridu period or Ubaid period (6500 - 3800 BCE).
The Roman numerals (eg Uruk XVIII, VI, IV, etc), indicated which each level of city's period of existence. Like many cities throughout the Near East, people would built their city on top of the older ones, like Ur, Damascus, Meggido and Jericho.
Jericho for example, have over 20 layers of settlement.
Anyway, back to Uruk. The oldest cuneiform writings were found in Uruk IV, in which later Sumerian cuneiform evolved from. Sumerian civilisation didn't start until around 3150 BCE, which coincide with making bronze tools, hence the start of the Bronze Age.
The Nimrod's story (Genesis 10) is a myth, because Uruk (Erech), Akkad (Accad), Babylon, Nineveh, Calch have all originated in different times in history, which datings have proved. They weren't built by one man.
Likewise, prehistoric Egypt, along with cultures predated the Bronze Age (hence before the 1st dynasty), by at least a thousand year (eg Chalcolithic Egypt, making use of copper tools, have been dated from c 4400 to c 3150 BCE).
One of the oldest cities in Egypt was Nekken. Its earliest Neolithic settlement dated to around about 4500 BCE, but it was around 3500 to 3400 BCE, that Nekken became a major city in Upper Egypt, reaching its zenith in the next two centuries (c 3300 to c 3150 BCE), when it became political capital of Upper Egypt, as well as religious capital, mostly sacred to Horus. Around 3400 BCE, there were as many as 10,000 residents in Nekken.
Nekken have artefacts that demonstrated the Egyptian culture slowly evolve from the older and more primitive culture to the more distinctive “Egyptian” quality that Egypt is known for. The evolution show the continuity of Egypt’s history was developed in stages.
The notion that Egypt didn't exist until after the Flood (see Genesis 10, where Egypt is sometimes translated to Mizraim), is not only wrong, but a myth.
Like Uruk and Nineveh, Egypt is far older than Genesis 10 gives credit for. So it is clear to me, that the author of Genesis have no idea of the history of Egypt and Mesopotamia.
