Imagine an alternate history where the pyramids were only reappropriated but not constructed, by the Pharaos that we now regard as their tombs but instead as symbols for universal basic principles connecting all humans built around 10000BC. How would I build the proportions of the pyramids to encode what principles in it for possibly ten thousand years of absence of human intelligence?
It's an interesting thought experiment to consider how the pyramids might have been constructed if they were intended as symbols for universal principles rather than as tombs for pharaohs. If you were to create a structure intended to encode these principles and last for thousands of years, you might consider the following:

Choose the principles: Start by choosing the principles you want to encode in the structure. These could be ideas such as balance, harmony, equality, or any other concept that you believe to be universal and enduring.

Decide on the proportions: The proportions of the pyramids are based on the golden ratio, which is a mathematical ratio that is thought to be aesthetically pleasing. However, you may want to choose a different ratio or set of ratios that are significant to the principles you want to convey.

Determine the materials: The pyramids were constructed from large blocks of limestone, but you may want to consider different materials that can withstand the test of time, such as granite or basalt.

Consider the placement: The pyramids are located on the west bank of the Nile, facing the setting sun. You may want to consider the placement of your structure in relation to natural or cosmic phenomena that are significant to the principles you want to convey.

Incorporate symbolism: The pyramids contain various symbols and hieroglyphics that convey meaning. You may want to incorporate your own symbols or hieroglyphics that represent the principles you want to convey.

Overall, the key to building a structure that will endure for thousands of years and convey universal principles is to think carefully about the design, materials, and symbolism, and to ensure that these elements are aligned with the enduring principles you want to convey.
