A technologically advanced global civilization existed before the Younger Dryas and was wiped out in a cataclysm around 12,900 years ago: the thesis of Graham Hancock's Netflix series Ancient Apocalypse.

Hancock's core claim in Ancient Apocalypse, that an advanced global civilization was destroyed by a comet-triggered cataclysm at the onset of the Younger Dryas (roughly 12,900 years ago), and that its survivors seeded the earliest known civilizations in Egypt, Mesopotamia, and Mesoamerica, runs into the same problem every time it's checked against physical evidence: there isn't any. No city, no agricultural system, no writing system, no metallurgy predating the well-attested Neolithic transition has ever been found anywhere on earth. The Younger Dryas Impact Hypothesis itself, which Hancock leans on heavily, remains unresolved and contested within the relevant geology and impact-science community: critics including impact physicist Mark Boslough and archaeologist Vance Holliday have pointed to the absence of a confirmed impact crater and to disputed interpretations of the nanodiamond and platinum evidence offered as proof of an impact event. Hancock's flagship archaeological example, Göbekli Tepe, is well-explained within the standard chronology as an early Neolithic hunter-gatherer ritual site built without metal tools, agriculture, or writing: evidence of surprisingly early monumental capability among hunter-gatherers, not evidence of a prior lost civilization's leftover engineers.

What makes this thesis worth engaging theologically, rather than only archaeologically, is that Hancock explicitly reads flood traditions found across many disparate cultures as corroborating evidence for his cataclysm, including, by his own account, treating the Noah narrative as based on the same real event. That puts his thesis in direct competition with Genesis 6-9's own explanation for exactly the same data point: why so many unrelated ancient cultures preserve catastrophe-and-rebuilding traditions. Answers in Genesis reviewed Ancient Apocalypse specifically on this point and staked out real, documented engagement with Hancock's flood claims: they argue Hancock is right that these flood legends are too widespread to be coincidence and likely do point back to a real remembered event, but wrong about which event, when it happened, and why: AiG holds to a global Flood dated by the biblical genealogies to roughly 4,350 years ago, not a localized Younger Dryas-era cataclysm around 12,900 years ago, and criticizes Hancock for rejecting the Bible's own historical framework (creation, the Flood, Babel) while still implicitly borrowing its intuition that a real ancient flood happened. That is a genuine, citable instance of Christian apologetic engagement with Hancock's specific thesis: it should be read as one documented young-earth apologetics response, not as the only possible Christian answer, since other biblically-grounded readings of the Flood narrative (including old-earth and more localized-flood interpretations held by various evangelical scholars) engage the same widespread-flood-tradition evidence differently. Genesis 6:17 states the flood's cause and scope in the text's own terms (divine judgment, not comet debris), which is the point any naturalistic rival account, Hancock's included, has to reckon with rather than simply ignore.
