This is a more detailed comparison between the Book of Two Ways and plausible routes into Africa during the African Humid Period (12,800 BC - 3500 BC, peak period ~7500 BC).

If it can be shown, that it is more likely than not that the Book of Two Ways is a map of two potential optimal routes from the Chotts, through desert into humid Africa it would imply Rosetau (mouth to passages/passages), Aaru (the field of reeds) and Sekhet Hetepet (the field of offerings) are descriptions of real destinations along this plausible route. This would imply Egypt was preserving this geographical information across millennia. This would imply Egypt was preserving information across millennia and would have serious implications for our understanding of Egypt. This is relevant to Atlantis because it would in-turn have implications for the plausibility of Atlantis as a Egyptian memory of Sekhet Hetepet in the green Sahara.

It is entirely conceivable that early people once took this route, there is cave art of this period in the hills at the bottom of the image, this in itself wouldn't be contentious.

My verdict on this is that its difficult to believe that Egyptians through coincidence alone drew up an elaborate route map to fertile regions which happens to align very closely to nearby real routes people may have once taken.

The precipitation data is from the most accurate available study which models precipitation for 4000 BC, ‘Wetlands of North Africa During the Mid-Holocene were At Least Five Times the Area Today 2021’. Using their recommended MH3 model. 4000 BC is past the peak period of humidity but it is also closer to the last period these routes may have been viable.

The rivers and streams come from river maps in ‘Ancient watercourses and biogeography of the Sahara explain the peopling of the desert 2010’ modelling streams and rivers in 9000 - 6000 BC.
