This stuff really fascinates me. Like you say, anomalous archaeological finds pop up all around the world, and most are relegated to the fringes of science, rather than receive the sort of serious study they merit.
Anything dug up that doesn’t fit the pre-ordained and agreed-upon story of human habitation and civilization is automatically ruled “impossible” by the so-called experts.
Ever hear of Michael Cremo? He wrote a book called “Forbidden Archaeology” about a decade back, which is all about these incredible finds.
Anyone with the means to grasp or reject the narratives of that book would find it worth reading at least once. Many, but not all the objects presented are subject to manipulation.
