The Short Truth Is, No One Really KnowsBut estimates suggest each pyramid could have taken somewhere between 15-30 years to complete. Around 118 different pyramids all across Egypt have been identified.

No. If anything, archaeologists have had more and more reasons to conclude that the Great Pyramid was constructed a little before the middle of the 3rd millennium BC, which is to say somewhere around 4600 years ago. Evidence includes: Associations.
The Greek historian Heroditus reported in the fifth century BCE that his Egyptian guides told him 100,000 men were employed for three months a year for twenty years to build the Great Pyramid; modern estimates of the number of laborers tend to be much smaller.
With modern-day tools and know-how, scientists have not determined a way to recreate the pyramids, even on smaller scales, with the same precisions as those that built the originals. The technology to do so, in that era, simply didn't exist according to historical teachings.
For starters, Egyptian pyramids are way older. The oldest known pyramid in the world is the Pyramid of Djoser in Egypt, which dates back to the 27th century BCE (2700 – 2601 BCE). Comparatively, the oldest pyramid in the Americas is thought to be the La Venta pyramid (394-30 BCE) in the Mexican state of Tabasco.
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.
In addition, they used stone like granite: a material so hard that it wouldn't act like a sponge – the water didn't penetrate it. So, the stone would shed the water and the building would last longer.
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.
Considering the pyramids were built more than four thousand years ago, the exact technique of construction remains a mystery and modern-day equipment was not available at the time. It is believed that ancient Egyptians ferried the huge stone blocks on the Nile river.
Civilizations like the Olmec, Maya, Aztec and Inca all built pyramids to house their deities, as well as to bury their kings. In many of their great city-states, temple-pyramids formed the center of public life and were the site of holy rituals, including human sacrifice.
In short, the Maya came first, and settled in modern-day Mexico. Next, came the Olmecs, who also settled Mexico. They didn't build any major cities, but they were widespread and prosperous. They were followed by the Inca in modern-day Peru, and finally the Aztecs, also in modern-day Mexico.
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.
They used levers to lift the capstone to a height of 20 feet (6.1 m). Four or five men were able to use levers on stones less than one ton to flip them over and transport them by rolling, but larger stones had to be towed.
