Nabta Playa, Hieraconopolis and Buto

Let us first look at some wikipedian articles, involving Egyptian chronology:

Nabta Playa, 22°30.5′N 30°43.5′E:
https://en.wikipedia.org/wiki/Nabta_Playa

Nabta Playa was once a large internally drained basin in the Nubian Desert, located approximately 800 kilometers south of modern-day Cairo[1] or about 100 kilometers west of Abu Simbel in southern Egypt,[2] 22.51° north, 30.73° east.[3] Today the region is characterized by numerous archaeological sites.[2] ....

Archaeological findings may indicate human occupation in the region dating to at least somewhere around the 10th and 8th millennia BC.[2] Fred Wendorf, the site's discoverer, and ethno-linguist Christopher Ehret have suggested that the people who occupied this region at that time were early pastoralists, or like the Saami practiced semi-pastoralism (although this is disputed by other sources because the cattle remains found at Nabta have been shown to be morphologically wild in several studies, and nearby Saharan sites such as Uan Afada in Libya were penning wild Barbary sheep, an animal that was never domesticated). The people of that time consumed and stored wild sorghum, and used ceramics[2] adorned by complicated painted patterns created perhaps by using combs made from fish bone and which belong to a general pottery tradition strongly associated with the southern parts of the sahara (e.g., of the Khartoum mesolithic and various contemporary sites in Chad) of that period.[2] Analysis of human remains by Fred Wendorf and reported in "Holocene Settlement of the Egyptian Sahara", based on osteological data suggests a subsaharan origin for the site's inhabitants.[4]} Several scholars also support a Nilo-Saharan linguistic affinity for the Nabta people; including Fred Wendorf and Christopher Ehret.[citation needed]

By the 7th millennium BC, exceedingly large and organized settlements were found in the region, relying on deep wells for sources of water.[2] Huts were constructed in straight rows.[2] Sustenance included fruit, legumes, millets, sorghum and tubers.[2]

Also in the late 7th millennium BC, but a little later than the time referred to above, imported goats and sheep, apparently from Western Asia,[5] appear. Many large hearths also appear.[2] ...

By the 6th millennium BC, evidence of a prehistoric religion or cult appears, with a number of sacrificed cattle buried in stone-roofed chambers lined with clay.[2] It has been suggested that the associated cattle cult indicated in Nabta Playa marks an early evolution of Ancient Egypt's Hathor cult. For example, Hathor was worshipped as a nighttime protector in desert regions (see Serabit el-Khadim). To directly quote professors Wendorf and Schild:[2]

By the 5th millennium BC these peoples had fashioned what may be among the world's earliest known archeoastronomical devices (roughly contemporary to the Goseck circle in Germany and the Mnajdra megalithic temple complex in Malta). These include alignments of stones that may have indicated the rising of certain stars and a "calendar circle" that indicates the approximate direction of summer solstice sunrise.[6] "Calendar circle" may be a misnomer as the spaces between the pairs of stones in the gates are a bit too wide, and the distances between the gates are too short for accurate calendar measurements."[4] An inventory of Egyptian archaeoastronomical sites for the UNESCO World Heritage Convention evaluated Nabta Playa as having "hypothetical solar and stellar alignments."[7] Claims for early alignments and star maps

Astrophysicist Thomas G. Brophy suggests the hypothesis that the southerly line of three stones inside the Calendar Circle represented the three stars of Orion’s Belt and the other three stones inside the calendar circle represented the shoulders and head stars of Orion as they appeared in the sky. These correspondences were for two dates—circa 4,800 BC and at precessional opposition—representing how the sky "moves" long term. Brophy proposes that the circle was constructed and used circa the later date, and the dual date representation was a conceptual representation of the motion of the sky over a precession cycle.

Near the Calendar Circle, which is made of smaller stones, there are alignments of large megalithic stones. The southerly lines of these megaliths, Brophy shows, aligned to the same stars as represented in the Calendar Circle, all at the same epoch, circa 6270 BC. The Calendar Circle correlation with Orion's belt occurred between 6400 BC and 4900 BC, matching the radio-carbon dating of campfires around the circle.[3]

A 2007 article by a team of University of Colorado archaeoastronomers and archaeologists (three members had been involved in the original discovery of the site and its astronomical alignment)[8] has responded to the work of Brophy and Rosen, in particular their claims for an alignment with Sirius in 6088 and other alignments which they dated to 6270, saying that these dates were about 1500 years earlier than the estimated dates. ...

They propose that the area was first used as what they call a 'regional ceremonial centre' around 6100 to 5600 BC with people coming from various locations to gather on the dunes surrounding the playa where there is archaeological evidence for gatherings which involved large numbers of cattle bones, as cattle were normally only killed on important occasions. Around 5500 BC a new, more organised group began to use the site, burying cattle in clay-lined chambers and building other tumuli. Around 4800 BC a stone circle was constructed, with narrow slabs approximately aligned with the summer solstice, near the beginning of the rainy season.

More complex structures followed during a megalith period the researchers dated to between about 4500 BC to 3600 BC.

Buto, 31°11′47″N 30°44′41″E:
https://en.wikipedia.org/wiki/Buto

The city was an important site in the Predynastic era of Ancient Egypt that includes the cultural developments of ten thousand years from the Paleolithic to 3100 BC.

Hieraconpolis / Nekhen, 25°5′50″N 32°46′46″E:
https://en.wikipedia.org/wiki/Nekhen

The first settlement at Nekhen dates from either the predynastic Amratian culture (circa 4400 BC) or perhaps during the late Badari culture (circa 5000 BC). At its height from about 3400 BC, Nekhen had at least 5000 and possibly as many as 10,000 inhabitants.

... the religious and political capital of Upper Egypt at the end of prehistoric Egypt (c. 3200–3100 BC) and probably also during the Early Dynastic Period (c. 3100–2686 BC).

So, to resume (if you skipped the tables), and ignoring Ussher, the carbon dated time from 13 100 BC to 3400 BC, 9700 years, boil down to dates like between 2865 or even 2903 BC and 2208 BC - at most 700 years according to Syncellus - or like between 2850 BC and 1928 BC - at most 900 years, according to one try on St Jerome's chronology.

Funny, I recall starting to do details of one of the tables and then not finishing, I counted on finishing today and saw the work already done, was I doing it in a trance, or was a hacker benevolent and intelligent enough to finish my work for me?
