Nonsense of Noah

9.3. Short Time For MAJOR Accomplishments
When was "The Flood"?
(Source: Genesis, chapter 5)

4000 - God created Adam
3870 - Seth, son of Adam born
3765 - Enos, son of Seth born
3675 - Cainan, son of Enos born
3605 - Mahalaleel, son of Cainan born
3540 - Jared, son of Mahalaleel born
3378 - Enoch, son of Jared born
3313 - Methuselah, son of Enoch born
3126 - Lamech, son of Methuselah born
2944 - Noah, son of Lemech born
2444 - Shem, Ham, Japheth, sons of Noah born
2344 - The FloodGenesis 7:6 "And Noah was six hundred years old when the flood of waters was upon the earth".
2343 - Flood ended, waters receded

So, in 2343 BC, we started over with 8 people and two (or seven) animals of every kind.

Is it reasonable that all of the following could have happened SINCE 2342 BC?

Bare in mind that the population was heavily inbred, yet needed to discover and implement mathematics, engineering, astronomy, government, etc. in order to construct some of the things listed below.

The Egyptians
The prehistory of Egypt stretches from about 8000 BCE. The history, that is, what was written down at the time, stretches from ~3500 BCE through invasions by Hyksos, Hittites, Romans, through floods, famines, insurrections, twenty-odd ruling dynasties, massive building projects, and the mind-boggling minutiae of royal bureaucracy.

They also build Pyramids, the construction of which took thousands of people - some of them in the same year as the flood:

Construction dates of Egyptian Pyramids

The following table lays out the chronology of the construction of most of the major Egyptian pyramids. Each pyramid is identified through the pharaoh who ordered it built, their approximate reign and its location.
Pyramid / Pharaoh Reign Field
Djoser c. 2630 - 2612 BC Saqqara
Sneferu c. 2612 - 2589 BC Dashur
Sneferu c. 2612 - 2589 BC Dashur
Sneferu c. 2612 - 2589 BC Meidum
Khufu c. 2589 - 2566 BC Giza
Djedefre c. 2566 - 2558 BC Abu Rawash
Khafre c. 2558 - 2532 BC Giza
Menkaure c. 2532 - 2504 BC Giza
Sahure c. 2487 - 2477 BC Abu Sir
Neferirkare Kakai c. 2477 - 2467 BC Abu Sir
Nyuserre Ini c. 2416 - 2392 BC Abu Sir
Amenemhat I c. 1991 - 1962 BC Lisht
Senusret I c. 1971 - 1926 BC Lisht
Senusret II c. 1897 - 1878 BC el-Lahun
Amenemhat III c. 1860 - 1814 BC Hawara

Ask yourself how these could have been built immediately after the flood with inbred moron labor.

Here are some other major accomplishments that were accomplished shortly after the waters receded.

Stonehenge 3100 - 2400 BC

Great Wall of China started 500 BC
"Several walls, referred to as the Great Wall of China, were built since the 5th century BC."
There is ample evidence (artifacts) of civilizations existing in China prior to and after the flood.
How did a large population exist in China in the year 2500 BC if there were only 8 people alive (and no plants or animals)?
