Is it true we don t know how the pyramids were built?
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.

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.

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.
Scientists Just Revealed a Secret Corridor in the Great Pyramid of Giza—and It Could Lead to More. Egyptian antiquities officials have confirmed the existence of a hidden corridor above the main entrance of the Great Pyramid of Giza that dates back some 4,500 years, a discovery that could lead to further findings.
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.
Given that the Egyptian Pyramids have survived for over 4,000 years, the estimated time frames of 15 to 30 years that it took to build them seems relatively short.
rather than built by hand (by thousands of dedicated workers) as conventional science and history continually says. Some of these more “out there” ideas are likely born out of the fact that so much about the pyramids is still unknown, though. And physically exploring them up close is often impossible.
One of the biggest mysterious concerning the great pyramids is the big void in the great pyramid of Khufu, it is a chamber above the king's chamber around 100 feet (30 meters) and appears to have not been entered or damaged by tomb raiders. The Pyramids were not built by slaves.
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.
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.
Pyramids today stand as a reminder of the ancient Egyptian glorification of life after death, and in fact, the pyramids were built as monuments to house the tombs of the pharaohs. Death was seen as merely the beginning of a journey to the other world.
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.
