The construction of the Great Pyramid and the True History of Humanity revealed.
Very interesting and convincing documentary about the theory that ancient Egyptians built the great pyramids with concrete, at about 2500 BC.
The Egyptians were also the inventors of the metric system, the decimal number system, discovered the mathematical constant Pi (3.14) and other constants, created a mathematical geometry system, and used these number systems to build the pyramids to exact measurements.
They sailed to central and south America thousands of years before Columbus and used the knowledge they brought with them to build the central and south American pyramids with similar concrete and to similar measurements as in Egypt.
This ancient Egyptian knowledge was kept secret and passed down for thousands of years and discovered or 're-invented' by the ancient Greeks and Romans, then after about 1000 years of the dark ages, this knowledge was discovered or 're-invented' again during the European Renaissance starting in the 15th century.
A drop of water does consistently measure 1cm.
The video is 217 minutes (3:37:00) long, but at 1.5x speed only takes 145 minutes (2:25:00) to watch.
