OOPArts and the Simulation of the Existence of Remote Macro-Civilisations (RMC)

This study evaluates, through a geochronological plausibility simulation, the potential existence of anatomically modern and technologically advanced Remote Macro-Civilisations (RMC) in periods preceding official chronology. By integrating the framework of the Silurian Hypothesis [1] with archaeometric protocols, the study isolates the presumed Out-of-Place Artefacts (OOPArts) classified as Categories C (diagnostic and documentary deficit) and D (unresolved historiographical inconsistency), excluding confirmed forgeries (Case B) and underestimates of ancient technological capabilities (Case A). The statistical-distributional analysis of three series of finds – dating back to 5 Ma, 60 Ma and 400 Ma respectively – reveals a density of anomalies that is inversely proportional to the age of the host sediment. This trend, consistent with rates of diagenesis, biogeochemical degradation and exogenic abrasion, suggests a non-linear and cyclical anthropogenic persistence on the planet. From a phylogenetic perspective, the morphological and aesthetic stasis of modern-type artefacts, footprints and anthropomorphic bone structures contrasts with Darwinian models of speciation and evolutionary divergence applied to primates. This inter-era phenotypic homogeneity, which is difficult to attribute to phenomena of convergent evolution from common non-human ancestors, introduces the theoretical plausibility of models of sequential and discontinuous exogenous colonisation (palaeocontact or controlled insemination).
