<p>[QUOTE=&quot;Alegandron, post: 2473933, member: 51347&quot;]I LIKE that term:&nbsp; &quot;Chronological Snobbery&quot;.</p><p><br /></p><p>It ALWAYS AMAZED me that the Egyptians built the Great Pyramids in the BEGINNING of their history!&nbsp; The 3 Great Pyramids of Giza were built during the FOURTH Dynasty, almost 2600 BCE.&nbsp; I also read that virtually HALF of ALL building materials used during the next 2500 years were consumed building those pyramids.&nbsp; AND, they were handling a lot of GRANITE in those constructions, which is some of the hardest stone materials to cut and shape.&nbsp; (Don&#039;t start the &quot;Aliens&quot; crap, it is just AMAZING what the Ancients were capable of doing...)&nbsp; Later construction down to the Ptolemies was using Sandstone, a much EASIER material to shape.&nbsp; So consider:&nbsp; over that time span, humans IMPROVED materials to make tools (Stone-Copper-Bronze-Iron-Steel), yet the BUILDING materials degenerated from handling HUGE amounts of granite (no, the Pyramids were NOT completely made from granite, but a lot of cap-stoning and complementary pieces were cut and smoothed Granite) to using sandstone...&nbsp; That is an odd dichotomy in Manufacturing capabilities.[/QUOTE]</p><p><br /></p>
