Randall reads from a published paper that attempts to date the Great Pyramid using erosion patterns on foundation blocks that used to be partly covered by casing stones. Because we can pinpoint the time the casing stones were removed to within a few years, the erosion on the stone that used to be protected by the now-missing casing stones can be used to establish a baseline for the amount of time required for such erosion to occur. This can be compared to the erosion on the portions of the stone that was never protected, and thus a date for construction can be estimated. This leads us to studies on limestone erosion in general, and the evidence for catastrophic flooding along the Nile Valley, which leads us back to the Sphinx, and the erosion seen in the enclosure walls around it.Find Randall's channel here: https://www.youtube.com/therandallcarlsonAnd his website here: https://randallcarlson.com/You can support us through Paypal or Patreon by visiting our website: https://www.brothersoftheserpent.com/support
