But what the Egyptians lacked in tools, they made up for with science and engineering precision. Smith explains that they developed and used the cubit rod to measure and lay out the dimensions of the pyramid; a square level to level horizontal surfaces, and a 3:4:5 framing square to create precision 90-degree angles.
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, ...

A hidden corridor nine meters (30 feet) long has been discovered close to the main entrance of the 4,500-year-old Great Pyramid of Giza, and this could lead to further findings, Egyptian antiquities officials said on Thursday.
The construction of the pyramids is not specifically mentioned in the Bible. What we believe about their purpose does not impinge on any biblical doctrine.
The archaeological team succeeded in detecting a unique system to move and pull blocks which can be dated to the reign of King Khufu at the latest. Most Egyptologists already think that Egyptians used ramp systems to build the pyramids, but there are different theories about what types they used.
To build such a pyramid today (using modern technology and equipment such as cranes and helicopters), it would take 1,500 to 2,000 workers around five years, and cost around $5 billion.
Attempted demolitionIn AD 1196, Al-Aziz Uthman, Saladin's son and the Sultan of Egypt, attempted to demolish the pyramids, starting with that of Menkaure. Workmen recruited to demolish the pyramid stayed at their job for eight months, but found it almost as expensive to destroy as to build.
Well, Napoleon did invade Egypt, and he fought a major battle within sight of the pyramids in 1798. It does seem that he visited the pyramids in person, although my Googling has turned up no records of him having shot them with a cannon.
Many people have said that the pyramids would last 1 million years or even until the world ended, but I'd say around 10,000 to 100,000 years based on current observations.
Egyptologists mostly take it as settled fact that the Sphinx was carved about the same time as the Pyramids with which it shares the Giza Plateau and that its gentle, enigmatic face (minus a nose, a beard and other bits that have fallen or been knocked off over the centuries) is actually the likeness of a Pharaoh of ...
In De-NileThe Nile Valley was the seat of an ancient Egyptian civilization that spanned over 4,000 years. In 3,000 B.C.E., Egypt looked similar geographically to the way it looks today. The country was mostly covered by desert.
