The relevance the astrological alignments of the Sphinx and the Pyramids have is found when you examine the rest of Hancock’s work around the world.Which shows various other structures and sites that also had many astrological alignments.When you consider that he thinks all these sites to be linked, you can see why he felt this to be important.

Population levels would have been small and communities necessarily mobile.

Moreover, the sites of the Great Sphinx, the Valley Temple and the Osireion were covered by a considerable depth of alluvial deposits at this time; if they had been built in the eleventh millennium BCE, they would have been at the bottom of pits 25 to 30 m deep!

Nevertheless, rainfall in the Nile valley itself remained low until about 9000 BCE, making settled life in the valley difficult.

These unfavourable climatic conditions virtually preclude the use of the Nile valley by the remnants of Hancock’s ‘lost civilisation’; hunter gatherers would have found few plants or animals to exploit, while farmland would have devastated by frequent floods and the shifting of the numerous braided river channels.

The river was sluggish and would have flowed in numerous braided channels.

As the ice caps shrank after 10,500 BC, an increase in rainfall at the headwaters of the Blue Nile in East Africa, combined with the White Nile breaking through the dunes in the Sudd, led to a brief period of exceptionally high floods, known to geologists as the ‘Wild Nile’.Hancock points to the stark simplicity of the temple, with its square sectioned columns, lack of inscriptions or reliefs and its construction techniques and suggests that it cannot be contemporary with the certainly Fourth Dynasty mastaba tombs scattered across the plateau.These tombs show greater architectural elaboration and were profusely decorated.Given that the rainfall of Egypt has remained at a low (if variable) level in historic times, Schoch suggested that the weathering ought to have occurred at a date considerably earlier than the conventional date of the monument, 2530 BCE.Schoch’s preferred date was the Neolithic Subpluvial of 7000-5000 BCE for the weathering, meaning that the Sphinx would have to be at least 2,500 years older than conventional Egyptologists believe.This geological evidence makes archaeological questions irrelevant.
