Culture‑Bringers Before History

This study applies the Necessity Method to twenty‑nine global traditions in which nonordinary agents transmit technologies, institutions, or social order to early humans. Narrative resemblance is separated from historical evidential weight through a dual grading system and conservative structural coding. A cross‑case audit shows a recurrent civilizational‑transfer grammar—external knowledge source, boundary placement, and multi‑capacity transmission—while an archaeological and palaeogenomic filter eliminates all surviving claims of unexplained technological discontinuity. Independently supported migration corridors, including the North Aegean–western Anatolia Neolithic route, provide historically ordinary pathways for narrative diffusion. The result is a falsifiable single‑origin narrative‑complex model constrained by external evidence, without requiring intervention by an advanced external or predecessor civilization
