Some people estimate 70 million mummies, but I think that's an underestimate. Mummification was carried out in Egypt, as I mentioned, for over 3,000 years. I'm sure more human mummies were made during this time period. If you look at animal mummies, several hundred thousand mummies have been found even in one cemetery. Countless mummies have been destroyed by tomb raiders seeking treasures within their linen wrappings.
As of November 2008, sources cite either 118 or 138 as the number of identified Egyptian pyramids. Most were built as tombs for the country's pharaohs and their consorts during the Old and Middle Kingdom periods. The earliest known Egyptian pyramids are found at Saqqara, northwest of Memphis. The earliest among these is the Pyramid of Djoser (constructed 2630 BCâ2611 BC) which was built during the third dynasty.
