For comparison, construction on Stonehenge is believed to started around 3100 B.C.E., while the famed Pyramids of Giza are thought to have been erected around 2600 B.C.E. at the earliest. That makes the roundel at least 1,000 years older than Stonehenge and several thousand years older than the pyramids.
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.
Ruins That Pre-Date The PyramidsOne of the main sites to discover that dates from before the pyramids is Abydos. It dates from around 7,000 years ago - thousands of years before the pyramids. Still, most of the actual ruins one will find there (like the Temple of Seti I) were built long after the pyramids.
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.
According to the Ancient Egypt Research Association (AERA), the architectural and geological evidence both support the conclusion that the Sphinx and its adjoining temple were built along with the rest of Khafre's pyramid complex, and were in fact among the last of the monuments to be completed.
The pyramids line up -- more or less -- along this line. The ancient Egyptians aligned their pyramids and temples to the north because they believed their pharaohs became stars in the northern sky after they died. But while the Great Pyramid is aligned with the north, the other pyramids are all slightly off.
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.
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.
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.
Many researchers agree that in the distant past, electricity was widely utilised in the land of the Pharaohs, with the Baghdad Battery being one of the most discussed examples of such advanced technology.
For example, the 18th Dynasty of the Egyptians dates from the 14th Century BC, whilst the Aztecs didn't begin to flourish in the Valley of Mexico till the 14th Century AD, making any contact or communication between the two cultures impossible.
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.
Legend has it that there is a maze below the paws of the Sphinx that leads to the mystery-shrouded Hall of Records, where all essential knowledge of alchemy, astronomy, mathematics, magic and medicine is stored. The library of knowledge - researchers continue to search for it today.
