At a glance
Genesis does not state a date tens of thousands of years before Abraham. Ross obtains that date by combining his reading of the genealogies with proposed identifications involving Peleg, Eden and an ice age. This site favors the shorter YEC chronology, while recognizing that identifying an ancient natural event with Noah’s Flood requires its own argument.
What Ross actually concludes
In the 2025 first edition, Ross concludes that the Flood occurred more than 40,000 years ago, very likely more than 45,000 years ago, and probably not more than 120,000 years ago. He regards 80,000–45,000 years ago as a more likely interval associated with ice-sheet melting, while retaining 120,000–45,000 years as a conservative range. Those are his model-based conclusions, not dates stated in Genesis. [1]
He connects Peleg’s division with disappearing land bridges, Eden’s rivers with proposed ancient geography, and the Flood’s slow recession with continuing snow and ice melt. He also discusses archaeological and linguistic indicators. These are more than a claim that every genealogy has gaps: the date requires several identifications and assumptions to work together. [2]
The biblical disagreement comes first
Genesis 5:1–32 and Genesis 11:10–32 contain ages tied to named descendants. This site reads those age-bearing formulas as chronological information and does not find a textual warrant for adding tens of thousands of years. The genealogy response explains why an omitted name and an unreported interval are different claims. Textual variants must be considered before presenting an exact sum; this article does not choose a creation-year calculation.
Genesis 10:25 names a division in Peleg’s days, but does not identify a drowned land bridge. Genesis 11:1–9 explicitly describes the scattering of humanity and confusion of language. Associating either passage with a specific prehistoric date requires evidence beyond a similarity in themes. Likewise, the river names in Genesis 2:10–14 do not by themselves establish that the modern river courses have remained unchanged through the Flood.
The Flood calendar in Genesis 7:11–8:19 specifies stages within the event. It does not say those stages were sustained by an ice-age melt. Neither does it supply a complete YEC account of the event’s hydrology.
What a dated observation can establish
A dated archaeological site or climate event can constrain a natural-history reconstruction. It does not identify its occupants with a particular biblical generation without another argument. Such observations may be independent of one another; it would be inaccurate to dismiss the entire exercise as circular simply because some identifications remain disputed.
Ross discusses a large discrepancy between dating methods at Jinmium and treats some early dates as upper limits. This response does not independently assess that case or accept the broader proposition that all relevant dating errors make results too old. A discrepancy in one example cannot establish the direction of every method’s error.
What remains to be shown
The YEC position here rests first on the narrative chronology. That preference creates a responsibility to address contrary scientific dating evidence, rather than declaring it invalid by definition. Ross’s ancient chronology similarly needs to establish the event identifications and genealogy intervals on which it depends. Rejecting one identification does not, by itself, establish a recent date for a geological deposit.
