The video cites estimates that two feet of limestone can erode in roughly 12,000–122,000 years under normal weathering, versus 1,200 years in a river environment. It points to heavily eroded megalithic structures near less-eroded structures assigned to the same period, including granite-cased examples, and argues that these contrasts support a much older timeline. The supplied sources do not substantiate the Giza-specific studies or establish that conclusion, which is not accepted in mainstream archaeology and Egyptology.
Video Argues Giza’s Differential Erosion Points to a Much Older Timeline
EgyptTheory
Key facts
- The video cites estimates that two feet of limestone takes 12,000–122,000 years to erode under normal weathering conditions.
- It cites a U.S. Army Corps of Engineers estimate of 1,200 years for two feet of erosion in a river environment; the supplied results do not identify a Giza-specific study corroborating this figure.
- The video contrasts heavily eroded structures it calls megalithic with less-eroded nearby structures conventionally assigned to the same period.
- It says some granite-cased structures show more erosion than comparable uncased structures.
- The video interprets the erosion contrast as evidence for a much older timeline; this is its argument, not an established archaeological finding.
