LifesBiggestQuestions claims a pre-flood kind of building in Japan, and it makes the case by touring the Oya stone quarry at Utsunomiya before turning to dolmens in Korea. Huge underground halls, cut in green volcanic rock, are presented as work the first diggers should not have managed with simple tools. The same script still gives a later timeline: small early pits, court and shrine use, tighter Tokugawa rules, and a guess that the imperial house opened the quarry. The rock is soft at the cut and firm once it meets air, which is why carvers could shape it. Tunnels are praised for depth, echo, and film sets. The Korea section asks whether dolmens were only elite graves or traces of giants, then describes rollers, ramps, and levers. A voice in that section says one monument began twelve thousand years ago, and another says megalithic dates should be reopened. That mix, not a dig report, is the channel’s older-than-the-usual-story claim.
Key points
- The channel frames the Oya caverns as nearly impossible work for the people who first cut them.
- A normal history of the quarry, from early pits through Tokugawa controls, is told alongside that claim.
- Oya rock is described as soft when quarried and hard after contact with air.
- Korean dolmens are then posed as possible elite graves or as giant-made monuments.
- Rollers, ramps, and sky alignments are offered as the builders’ methods.
- A inserted line dates one monument to twelve thousand years ago and urges a rethink of megalithic dates.
Short quotes
Fast forward to today, and despite our advanced technology and engineering prowess, replicating such a feat remains a formidable challenge.

It is relatively soft when first quarried, but hardens upon exposure to air.
