Some perplexing questions about pyramids:
- Did the Egyptians build pyramids?
- If so, why did the Egyptians build pyramids?
- Why did they stop building pyramids?
- How did they build them?
- Did they use an architect scale ruler to read their blueprints?
We consider the architect scale ruler to be a modern tool for engineers and planners. But since the Egyptians were so far advanced, why not assume that they used this modern tool, also?
