Hedman then turns his attention to means for dating the Great Pyramids of Egypt (circa 2500 BCE), introducing radiocarbon dating in the process.
The proportion has been effectively constant for thousands of years because the rate of formation of the radiocarbon from bombardment of the outer atmosphere by cosmic rays is balanced by its rate of radioactive decay.

Although the complete absence of geochronology, radiocarbon dates, or their contexts is troubling, this problem is not unique to Romain's book; rather, it is a sticky situation that has all but stifled archaeological studies in Ohio Hopewell (Greber and Ruhl 2001).
In this massively documented and closely reasoned work Sturt Manning, of the University of Reading, a well-known proponent of the Mediterranean "high" chronology, attempts to provide an absolute and precise chronological framework for Crete and the southern Aegean during the Early Bronze Age, or "Early Minoan" era, integrating the archaeological evidence with statistical analyses of the available radiocarbon and thermoluminescence dates.
New radiocarbon dates of cereal grains from debris left by the destruction of Jericho support several aspects of Exodus, the second book of the Old Testament that describes the departure of the Israelites from Egypt and their journey to the promised land.
