How about trial and error? The Great Pyramid is _far_ from the
first pyrimid that the Egyptians built. The first would be the Step
Pyramid. Shortly after that one the first "true pyramid" was built by
building a step pyramid and filling in the sides. Then pyrimids were
built of different heights and base sizes.
One particularly interesting case is the Bent Pyramid. This one
was started with exceptionally high and steep sides, as was another a
bit earlier. The earlier pyramid collapsed, leading to a hasty
redesign of the Bent Pyramid with less steep sides starting from the
point at which they learned of the trouble.
Build enough pyramids and you'll learn just from trying different
things what you need to get a certain result.
One thing that is all too often forgotten, particularly by the
new agey, crystal magicey, van danikenish crowd--people in earlier
times were _not_ stupid. They may not have developed much of the
theory, techniques, and technologies that we have today, but they were
as skilled with the techniques and technologies they did have as we
are with ours. Any theory about historical peoples that begins from
the premise that the peoples were stupid is suspect from the start.
