"The water erosion on the plateau pushes it out of Dynastic Egypt Timeline."
Although not discounting it (conditions prior certainly included a deluge), subsequent precipitation in the era c.4500 BC* onward, the interim, could also have been present, although flooding unlikely - I'll explain: just over 3 millennia ago, according to my model, at the time of min. obliquity, Earth's rotational axis flirted with the vertical - i.e. vertical to the ecliptic orbital plane. The North Pole, then, aligned with the constellation of Draco, near the vicinity of z-Draconis.
It is my contention that during the past 6,5 millennia, Earth's North Pole had shifted from alignment with Vega, in c.4500 BC, to Polaris in the present (applying numerical rounding). Midway of that quarter, circa 1200 BC, coinciding with the equinox, attaining min. obliquity.
We thus have a map of time, back in recent human history by 6500 years and the varying inclination of Earth's rotational axis in-between, which in that quarter, incurs obliquity variance in the order of 10 degrees...
This of course transfers in reduced tropic circle separation - the Sun's seasonal migration reigned in by 10deg of latitude N & S from the equator - the zone within affected by altered distribution of Sunlight and subjected to warmer temperatures, while the zone from the Pole to the Tropic experienced cooler temp. Ocean currents and conveyers, for instance, affected by the flux... precipitation, thus too eco systems, accordingly influenced...
In combination with that, although I have not studied wind and cloud formation sufficiently to accurately forecast/hind cast altered weather patterns :)) along latitude of the Sahara's location, it can be certain however, that there would be/was an impact.
Working in isolation is time consuming (between chores and survival requirements). Academia too removed due to precious institutionalized Phd's :-D or too threatened for obvious reason (add to that the weathering crowd now), as are alterno's - thus not 'us' and them, more like: 'me' and 'them' + 'them'... the adrenalin rush of combat - the irony, or hilarity rather, is the urging to strive to a mutual (low) standard of evidence... But hey, no worries, I am ahead of the pack... taking a breather, listening... the eerie silence, such as preceding a contact... quake or tsunami - in this case two precarious houses of cards... the debris and fall out is of concern, who will clean up after the rage of armageddon, create NWO?
sorry, I digress...
The preceding era, from which we just emerged, a quarter, 6500/26000 cycle remarkably entailed Earths axis undergoing a 180 degree change in orientation -- yet most representative of relative stability, with obliquity of Earth's rotational axis ranging from 24 deg. narrowing to 14deg. and back to 24deg., with balanced uniformity. Requires some specialized computer modeling to simulate - what universities usually play with but require entering of proper values (I'm outside the loop / club)
* preceding c.4500 BC - i.o.w. coming out of a 9750/26K turn around, equates to what we are currently entering: thus a 9,7millennia period either side of max. obliquity.
