No. To simplify Stel’s theory for TV, some very important details were left out.
First, all kinds of tools have been used by archaeologists to affix more accurate dates to to the lives of the pharaohs. From cataloguing pottery and ceramic assemblages, to dendrochronology, and Carbon 14 dating. As technology improves, and more evidence is collected, these dates continually shift by small increments.
Second, Egyptology has also settled into two camps when it comes to agreeing on the timing of Egyptian chronology. These are called High and Low. The Low chronology uses younger dates and is a more recent development. Stel ‘s theory relies on the more conservative High chronology.
When time allows Stel intends to recalculate his date based on the Low chronology.
Third, to complicate matters further, there are two parallel versions of Manetho’s king list since the original is lost and all there is left to work with are bits from other ancient writers.
