How was it possible to build the pyramids?

The most plausible one is that the Egyptians employed a sloping and encircling embankment of brick, earth, and sand, which was increased in height and length as the pyramid rose; stone blocks were hauled up the ramp by means of sledges, rollers, and levers.

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.

A little over 3,800 years ago, humankind began to build the tallest structure ever known to the world until then—the Great Pyramid of Giza. Humans managed this feat without any modern technology or tools, using only ramps, ropes, levers and sheer muscle power.

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.

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.

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, ...

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 square base of the Great Pyramid of Cheops, for instance, is just 3.4 arcminutes off of true north. That's a precision of about 1 millimeter per meter. Some of the later pyramids, however, deviate more, as if their architects' method for aligning them became less accurate over time.

The materials would also be very costly. I did an answer on the cost of building a pyramid in modern times, and it ran into the billions. Just the materials and labor of restoring the facing would cost a few tens of millions.

When it was built over 4,500 years ago, the pyramid of Khufu stood at 481 feet tall. But over the years, erosion has caused the pyramid to shrink down a bit. It now stands at 451 feet tall.

Alabaster came from Luxor and basalt from the Fayoum depression. Iron tools were not available, so workers used copper and stone-cutting tools to carve out the blocks in the quarries. They then used levers to move the stone blocks away from the quarry site.

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.

Elephants were never common in Egypt like they are in India today, so they were never part of the construction. It is the case that cows were used and we do have evidence of that, but in moving something as big as the obelisk it was most probably people power.

In 2014 a small raptor skeleton was uncovered in a small section deep within The Great Pyramid of Giza. The skeleton is presumed to have been unearthed in the building process by the ancient Egyptians and placed into the pyramid due to it being an interesting find (4). All in all the Pyramids were built by people.
