This program makes a number of factual errors thru exaggeration, hardly necessary considering the monumental achievement these structures are in their own right. They claim the Great Pyramid weighs 6,500,000 tons, enough to make 37 empire state buildings with millions of tons leftover. Actually, the Empire State building weighs in at 365'000 tons, so only about18 of them could be made from the Great Pyramid's total tonnage. That's impressive enough!
