How was it physically possible to build the pyramids?
“Using a sled which carried a stone block and was attached with ropes to these wooden posts, ancient Egyptians were able to pull up the alabaster blocks out of the quarry on very steep slopes of 20 percent or more.”

The Egyptians designed and used simple tools needed to build the pyramids. They used plumb bobs and square levels to ensure that corners of blocks were square and that surfaces were flat. These instruments were made of wood, twine, and lightweight stones.
The unknowns of pyramid construction chiefly center on the question of how the blocks were moved up the superstructure. There is no known accurate historical or archaeological evidence that definitively resolves the question.
It's still unknown exactly how the Egyptian pyramids were constructed, though the ancient Greek historian Herodotus estimated that 100,000 men labored for some 20 years to create the largest, the Great Pyramid, for Khufu.
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, ...
Although tourists were once able to freely climb the pyramids, that is now illegal. Offenders face up to three years in prison as penalty. In 2016 a teenage tourist was banned from visiting Egypt for life after posting photos and videos on social media of his illicit climb.
While there is no consensus on why this particular form of architecture appears so frequently in ancient civilizations, several theories have been proposed. One theory is the structural stability of the pyramid shape. The wide base and narrowing top provide a stable structure that can withstand the test of time.
The generally accepted theory is that the ancient Egyptians dragged the blocks on sledges over causeways made of either slaked lime or tafla (a local clay). The remains of causeways constructed of tafla have been found all over the Giza plateau (Hadingham 1992, p. 51).
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.
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.
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.
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.
Although it's believed that these structures hold some ancient secrets of the ancient Egyptian pharaohs, scientists have not been able to discover much. There are still questions left unanswered, and we are still waiting to know more. Also, there are interesting facts about these ancient marvels that you need to know.
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.
