If one starts to search for ``How were the...'' one of the first things to be suggested is, ``How were the Pyramids built''. The ``I feel lucky'' hit for that is:

Where it says, ``But the process of building pyramids, while complicated, was not as colossal an undertaking as many of us believe, Redford says. Estimates suggest that between 20,000 and 30,000 laborers were needed to build the Great Pyramid at Giza in less than 23 years. By comparison, Notre Dame Cathedral in Paris took almost 200 years to complete.''

``When answering to skepticism about how such heavy stones could have been moved without machinery, Redford says, "I usually show the skeptic a picture of 20 of my workers at an archaeological dig site pulling up a two-and-a-half ton granite block." He added, "I know it's possible because I was on the ropes too."''
How does one get ``No one knows how the Pyramids were built.'' out of that?
