According to Mr Malcolm Fabian of Mount Barker, South Australia, the
pyramids in Egypt had a practical purpose. After the flood on the
Nile, the boundaries between properties would need to be marked
again. So the stable pyramids were the reference, and the referencing
data was presumably a legal matter.

Then again, the stability of the pyramids led to more correct
observations of the stars, and their positional frequencies fixed time
periods, useful for planting and religious ceremonies.

In other words, in a changing surface, we need some absolute points,
like pyramids and stars, plus supportive logic and data, to come to
standards relating to time and space.

Cheers,
Arindam Banerjee
