Excavations led by Mike Parker Pearson, Richard Bevins, Rob Ixer and colleagues at Carn Goedog and Craig Rhos-y-felin document Neolithic megalith quarrying for Stonehenge bluestones around 3000 BC, published in Antiquity, against glacier-only and ancient-astronaut haul myths.
Nazca geoglyphs are archaeologically attested ritual/landscape features; 2024 Yamagata University / AI-assisted surveys nearly doubled known figurative geoglyphs, clarifying trail-associated motifs versus larger line figures—recenter peer-reviewed survey science over von Däniken runway myths.
Under the modern village of Sayburç in Şanlıurfa province, excavators working in 2021 opened a Pre-Pottery Neolithic communal building carved into limestone bedrock. On an interior bench they found a ~3.7 m horizontal relief of five interacting human and animal figures; Eylem Özdoğan published the panel in Antiquity in 2022 as narrative art from the ninth millennium BCE.
Seventeen known basalt colossal heads—ten from San Lorenzo, four from La Venta, two from Tres Zapotes, and one from La Cobata—anchor public memory of the Gulf Coast Formative societies archaeologists call Olmec. Faces differ; helmet-like headdresses recur; tonnage implies quarrying and transport systems capable of moving multi-ton blocks across the lowlands.
J. J. Benítez's 1983 book El Ovni de Belén applies UFO hermeneutics to the Matthean star and Nativity tradition—later echoed in Caballo de Troya 12: Belén (2022)—a documented Spanish interpretive claim inside Catholic-vs-ufology culture wars, not an astronomical proof that the Magi tracked a spaceship.
In 1980 J. J. Benítez published Los astronautas de Yahvé, reading Yahweh encounters and Old Testament wonders as astronautic theophany—a documented paleocontact thesis that prefigures his later interview line of Jesús as 'gran extraterrestre' and the Caballo de Troya theological science fiction.
Near Guanghan, Sichuan, Sanxingdui sacrificial pits—1986 Pits 1–2 and a 2020–22 wave—yielded extravagant bronzes, gold masks, ivory, and jade unlike the Central Plains Shang canon; Antiquity and Chinese excavation reports document ritual deposition against ancient-alien glosses.
In the Valley of the Kings, a doorway once dismissed as a minor, debris-choked entry belongs to KV5—the tomb of sons of Ramesses II and, after late twentieth-century clearance, the largest tomb complex mapped in the royal necropolis. Kent R. Weeks and the Theban Mapping Project relocated the entrance in 1987 while assessing tourism and road impacts, then spent years clearing flood-hardened fill.
