Perhaps, one day soon, we shall be properly introduced to "Rockwall" aka "Petra Rocas" / "Pelius" / "Pelias" / [the first] "Petra" ancient kind SVAR [Nabatean] civilisation... with Cyclopean masonry foundations dating back c 1,000,000 years. Then came the other Petras... post-cataclysms of 800,000 years ago and 11,700 years ago, the latter cataclysm sealing Rockwall's fate in the Neolithic. https://youtu.be/Fu74Yeh-CtE?t=25
