Egyptian chronology and the Bible—framing the issues
by Gary Bates
https://creation.com/egypt-chronology


I am basically going to concentrate on two things:

  • what he says on carbon 14 (14C for short)
  • what he says of the New Kingdom


  • To assist with dating artifacts from Egypt, carbon-14 dating is now extensively used but widely disputed due to the massive revisions in time it can lead to. We have written much about the alleged absolute reliability of 14C dating.


    I do in fact not hold to the absolute reliability of 14C dating. However, I have much more confidence as to its relative reiability than CMI generally have. There are factors in the problem they persist in ignoring. Robert Carter offered me this "explanation" (it was obviously clear to him that I was not promoting taking "40 000 BP" as really 40 000 years ago) of why they do not even attempt such a thing:

    This period covers some of the most important periods of biblical history, yet carbon dating fails to properly date any of it. If we have rapidly rising 14C levels, we cannot even assume the atmosphere would be fully mixed during the transition period. Throw in an Ice Age, shifting atmospheric circulation patterns, vast amounts of old carbon being dumped into the biosphere via vulcanism and via the erosion of calcium-containing rocks, a collapsing magnetic field, and who knows what bombarding us from outer space, and I fully suspect that the oldest measurements will be far from precise.


    The problem is, the more 14C levels punctually sink because of release of old carbon, and note the release of old carbon from 1750 to 1950 has contributed to such a decline in 14C levels that 1750 having dated to 1950 (raw, uncalibrated date), 1950 dated to 1750 (dito). As said, the more the level punctually sinks, the more drastic increases have to be taken in as to cosmogenic 14C which implies radioactivity.

    If the levels rose from just above 1 pmC in the Flood 2957 BC to 82.73 pmC in 1935 BC when Genesis 14 happened (Abraham around 80 years, or between 76 and 85), the medium factor of how much more 14C was produced each year can be calculated as this:

    2957 - 1935 = 1022 years (it will be radically less in the Masoretic timeline), implies a decay from 100 to 88.37 percent of original level, and therefore also a normal replacement of 100 - 88.37 = 11.63 pmC.

    1.628 * 88.37 / 100 = 1.439 remaining pmC*
    82.73 actual pmC
    82.73 - 1.439 = 81.291 pmC replacement.

    81.291 / 11.63 = 6.99 times faster.

    Let's follow this up as to what this implies midway or rather 401 after the Flood, when Peleg was born.

    401 years, decay 100 to 95.265, normal replacement 4.735 pmC

    1.628 * 95.265 / 100 = 1.551 pmC
    6.99 * 4.735 pmC = 33.097 pmC
    33.097 + 1.551 = 34.648 pmC

    2556 BC + 8750 extra years = dates as 11306 BC (in my view, 2556 BC actually dates as 8000 BC, and the level is 51 pmC and some).

    Now, to account for the supposition of Carter, let's suppose old carbon to a quantity comparable to the one dumped between 1750 and 1950 is dumped by some volcanic activity.

    In order to do this, I need to speak of pmC levels above 100 meaning dates "into the future", because that's what things start out with in 1750. I'm going back to my usual carbon 14 dating calculator, so we are now using numbers from two different apps. In 1750, the level was 102.449 pmC. We'll suppose this sinks to 1950 to 100 pmC, meanwhile the level in 1950 is actually 97.61 pmC.

    What exact addition of old carbon to the overall CO2 has this effect?

    X = 100 pCO2 => 100 pmC
    X = 200 pCO2 => 50 pmC
    X = 150 pCO2 => 75 pmC
    X = 112.5 pCO2 => 87.5 pmC
    X = 106.25 pCO2 => 93.75 pmC
    X = 103.125 pCO2 => 96.875 pmC

    So, adding 3.125 pCO2 (or percent atmospheric carbon, I improvised the term) is a thing. While it took 200 years, we'll suppose it happened in one go, 401 after the Flood. Actual post-Babel dates would then date prior to the date 11 306 BC.

    X = 100 pCO2 => 34.648 pmC
    X = 103.125 pCO2 => 33.565 pmC

    So, next year, 2555 BC, you add instead the extra years 9000, giving 11 555 BC. I don't find it very convincing that a sudden addition of old carbon could have happened more than 200 times faster than it did in the industrial era, but have at it.

    In 2555, the pmC has instead halved. That would imply that reaching 34.648 pmC actually only took 3.495 times faster production, since the time from flood to 2556 BC would have had only half of our atmospheric carbon. But, 2555 BC, we have present levels of atmospheric carbon, half of which was back then old carbon, it is terribly badly mixed, but the medium level would be down to 17.324 pmC.

    2555 would range from 37 000 BC to 11 306 BC, but tend to date around 17 055 BC.

    However, 2555 BC, carbon-14 level is on medium 17.324 pmC.

    1022 - 402 = 620 years. Decay 100 to 92.774, normal replacement 7.226 pmC.

    17.324 * 92.774 / 100 = 16.072 remaining pmC
    82.73 - 16.072 = 66.658 actual replacement pmC
    66.658 / 7.226 = 9.225 times faster replacement.

    The extra years and therefore 14C levels would differ in Masoretic chronology, but not too much. I'll be inaccurate enough to insert the values from here to those other years. For Ussher years, I'll access Haydock.

    Year of the World 2092, Year before Christ 1912 = Genesis 14
    Year of the World about 1800, and Year before Christ 2204 = (end of) Babel

    2204 - 1912 = 292 years. 620 / 292 = 2.123 faster overall process.
    2.123 * 9.225 = 19.587 times faster 14C replacement/production

    And that's just if you want to put Magdalenian in post-Babel instead of pre-Babel, it gets worse if you want to put Neanderthals and Denisovans in the post-Babel instead of the pre-Flood.

    But between Genesis 14 and ... let's say fall of Troy, 1180 BC ... the rise is either way slower.

    1935 - 1180 = 755 years, decay from 100 to 91.272, normal replacement = 8.728 pmC.
    Or, if you prefer, 1912 to 1180, not much difference.

    82.73 * 91.272 / 100 = 75.509 remaining pmC
    100 - 75.509 = 24.491 actual replacement pmC
    24.491 / 8.728 = 2.806 times faster

    Note, from Genesis 14 to Fall of Troy, a period that spans the Exodus, this slower rise will likely be less irregular, since better mixed, since the 14C production more closely resembles the present one. This is the context in which one should take my comment under a video by Gary Bates:

    1446 + 430 = 1876 (at the promise, 430 years prior to Exodus).
    1550 - 1406 = 144 extra years at the taking of Jericho.

    [etc]

    Jacob going to Egypt would be in 215 after the promise, i e in 1661.

    What would the C14 level be then?

    215 years is 97.433 % and 2.567 pmC replacement.

    82.164 * 97.433 / 100 = 80.055 pmC
    80.055 + (2.567 * 3.736) = 89.646 pmC

    89.646 pmC => 900 extra years.

    1661 + 900 = 2561 BC. That carbon date is well before the Hyksos. It's actually not too far from Djoser.


    Obviously, at Gary Bates' Exodus dating, we get to 100 pmC even before Fall of Troy, namely in the Exodus. The result is that the rise from Genesis 14 on would be even steeper. Not too steep to be fairly even, but still steep enough. Even clearer disproof of a Hyksos pharao, when Joseph arrived. But suppose instead we actually allowed a Hyksos pharao for Joseph.

    Year of the World 2298, Year before Christ 1706. = Genesis 43 (Ussher chronology)
    The Second Intermediate Period c. 1700–1550 BC

    So, 100 pmC, not just for Exodus, but even Joseph's receiving the brethren.

    1912 - 1706 = 206 years. Decay 100 to 97.539. Normal replacement 2.461 pmC.

    82.73 * 97.539 / 100 = 80.694 remaining pmC
    100 - 80.694 = 19.306 actual replacement pmC.
    19.306 / 2.461 = 7.845 times faster replacement.

    So, the scenario given by Gary Bates involves on the one hand, the 14C production continued to be much faster than today, nearly 8 times faster, up to Joseph in Egypt, and then came to rest flatly on the modern production level, so that Kenyon's inflated dating for Jericho must be due to mismanagement on her part, rather than 14C level that was still somewhat lower than what would equate carbon date to real date. How exactly does Gary Bates defend this?

    Famous Egyptologist Zahi Hawass, who at the time of the 2010 report was secretary-general of the Egyptian Supreme Council for Antiquities, said:

    “This technique shouldn’t be used at all in making changes to the chronology of the [sic] ancient Egypt, not even as a helpful addition … carbon dating is useless. This science will never develop. In archaeology, we consider carbon dating results imaginary.”32


    Well, but what is his rationale? If we look at conventional carbon dates, calibrated according to a presumed 14C level close enough to 100 pmC, this more or less adds up to the totals, but it will make a trainwreck of the details in Egyptian "documented" chronology and succession of pharaos. Zahi Hawass may be very famous, but he is not a Young Earth Creationist and is therefore not prepared for a wholesale adaption of Egyptian chronology to the Biblical one, starting with Abraham meeting Narmer or one of his predecessors in Lower Egypt, before the unification. Or even maybe one of the guys in Upper Egypt whom Narmer defeated later on. However, I am, and Gary Bates should be, prepared for such reevaluation. Therefore, Zahi's premiss being flawed, his conclusion is flawed too.

    Again, it shows how much disparity there is in trying to reconcile timelines for ancient Egypt as no one source seems to be consistent with any other and many preconceived ideologies and agendas rule. The further back in ancient Egypt one tries to use 14C dates the more disparate the figures are also likely to become. Also, because there are fewer artifacts from the more ancient dynasties the more likely it is that researchers will rely upon 14C alone as a single line of evidence. Hence, why an Old Kingdom revision can occur in the blink of an eye by c. 400 years. This is less likely with New Kingdom dates where we have a wealth of more recent evidence to confirm or reject a 14C date.


    While the New Kingdom is better documented, it is not all that well documented that a revision of 100 years along the start is impossible. I would say, the New Kingdom starts at the carbon date 1550 BC, same as for Kenyon's date for Jericho. This means, the real date 1470 BC, 40 years after the Exodus, when Joshua conquers Jericho. Or in other words: the Hyksos were Canaaneans, when Joshua weakens these, or God does so through Joshua, he helps to liberate Egyptians from them as well.

    In this context, I recall another video, with Gary Bates, where he gave specific arguments for a specific New Kingdom pharao. I made responses, and posted them on my blog, and now I cannot find the blog post. Not on either of the blogs where I would expect to find it, neither this one, nor the one called Assorted Retorts. Maybe he put that video down to replace it with the one from 27 March this year. If he did, let's hope he didn't arrange to have my post deleted for supposed "copy-right" issues, refuting is not plagiarising, in US law, but perhaps he could find a dishonest and accomodating internet admin. Or, for that matter, let's hope he didn't do so without deleting the previous video either. Whoever did it can be considered as committing inimical acts against me, and exercising a kind of illegal censorship. And especially an immoral one.

    The take-away I hoped to provide through the citation of my previous criticism is, anyway, that the kind of astronomic event associated with that particular pharao that Gary used to clinch the date, also occurred some 20 or 50 years later, whichever it was, it would have been compatible with my dates for the Exodus and revision of the New Kingdom.

    Meanwhile, an Exodus in 1510 BC (carbon dated to perhaps 1609 BC, if God used the Santorini eruption as partial cause for the plagues of Egypt) would from Gary Bates' perspective have the disadvantage of putting more time between the Exodus and the Temple than 480 years. On this issue I refer back to my conclusion that "480 years" is intended to mean "at least 480 years":

    It is possible that the material on what pharao Gary Bates had in mind is still there in another video, not taken down, and that even my comments would be accessible to me. It is possible that it is only on the new video. I'm sorry, but due to internet sabotage, I will have to return to that later.
