Dang those Egyptians are smart.
Actually, they were 'smarter' than we are.
They knew how to build the Great Pyramid, we do not.
So much for the theory that as civilization grows it gets more intelligent.
Actually I believe the Egyptians, and many middle eastern countries, had many varieties of fermented beverages, from wine, to beer, to what we call moonshine.
How long has JAPAN had sake? Thousands of years?
Utilizing the technology of the day, about the only tall imposing structure that COULD be build, was, by necessity, a pyramid.
There is no great mystery or unknown techniques required to build a pyramid like the Egyptian ones, and we could do so with modern technology much quicker and with much less manpower.
