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.
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.
It was the Egyptians who built the pyramids. The Great Pyramid is dated with all the evidence, I'm telling you now to 4,600 years, the reign of Khufu. The Great Pyramid of Khufu is one of 104 pyramids in Egypt with superstructure. And there are 54 pyramids with substructure.
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.
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.
They don't sink because they're built on solid limestone. If the ancient Egyptians were just amateurs building their huge monuments on sand, time would have erased all traces of them during the past 5000 years.
Yes, there are pyramids located in the United States. However, these pyramids are not as well-known as the pyramids in Egypt or Central America. One example is the Monk's Mound located at Cahokia Mounds State Historic Site in Illinois.
There are rooms that have been discovered in the Great Pyramid, but are not open to the public. The original tomb chamber, which is underground, is closed off.
