Did the pyramids have electricity?

How long would it take to build the pyramids today?
While the pyramid was originally built by 4,000 workers over the course of 20 years using strength, sleds and ropes, building the pyramid today using stone-carrying vehicles, cranes and helicopters would probably take 1,500 to 2,000 workers around five years, and it would cost on the order of $5 billion, Houdin said, ...

How many years did it take to build the pyramids?

How did sphinx lose its nose?
In 1378 CE, Egyptian peasants made offerings to the Great Sphinx in the hope of controlling the flood cycle, which would result in a successful harvest.
