Was our solar system designed to produce humans? (cont.)
By Christopher Knight and Alan Butler
Artifact based evidence
When we wrote Civilization One we stated that the people who created the Megalithic Yard must have built very large circles and divided the circumference into 366 parts to be sure that they were viewing 1/366^{th} part of the night sky. We suggested that they may well have understood a quick method to do this by making a circle with a diameter 233 units (any length would do if they didn't already have a Megalithic Yard). They then knew that they would have a circle of 732 units  which is twice 366, so they could take every other pole on the circumference. This is a 99.999% accurate means of using pi in a practical manner. For all engineering purposes this means perfect.
Several years later we found that structures even older than the Megalithic structures demonstrated the use of the 233/732 circles  exactly as we had predicted. These are henges  large circular mounds such as the group near Thornborough in North Yorkshire, England. They where built around 3500 BC, well before the Megalithic builders began their stonework phase. What is more they were using the Megalithic Yard, or the 'Thom' as we now call the geodetically refined value of the same length. At Thornborough there are three interlinked henges that are 233 Thoms across and 732 Thoms around their outer perimeter. These structures about with units and ratios being 366 Megalithic Rods between the centers of the first two and 360 between the second. The trio, which are also exactly 3 Megalithic seconds of arc apart by latitude, have also been identified as being laid out as a copy of the stars of Orion's Belt  exactly like the Giza pyramids. The difference is that these are a thousand years older. We also explain in 'Before the Pyramids' how Khufu's pyramid builders came to this location in England to get instructions on how to plan this star pattern on the ground!
The Thornborough henges, a perfect copy of the stars of Orion's Belt. A to B is 366 Megalithic rods, B to C is 360 Megalithic rods and the true north/south latitudinal distance (in Red) is 3 Megalithic seconds of arc.
Weights and Measures
Having established that the people of the British Neolithic had units of lengths and time, we wondered if they had other units such as capacity and weight. We knew (or so we thought) that the Metric system was devised by the French in the late 18^{th} century when they used a pendulum that beat at the rate of one second to create a unit they called the metre(meaning to beat out time). They later made a very small adjustment so that their metre was one 10,000,000^{,th} of the distance from the equator to the north pole. To create a unit of capacity they took a 1/10^{th} part of the metre (10cm) and made a cube. Filled with distilled water, this cube's capacity was called a litre and its weight was designated a kilogramme.
We applied the same logic to the Megalithic Yard, (which Alexander Thom said was divided into 40 Megalithic Inches). So we calculated what a 4 Megalithic Inch cube would contain. The answer is one pint  to an accuracy of one part in 5,000 as defined by the British government in 1601. And when carefully filled with any unpolished grain, such as barley, it weighed just one Imperial pound.
This was odd in the extreme but it appears that (unknown to history) Imperial units were indeed based on cubes because by doubling the sides of the cube to 8 Megalithic Inches holds one Imperial gallon and doubling again produced a unit equivalent to a bushel, which was used as a dry weight until recent times.
Next, we found some truly bizarre connections. We thought for thoroughness that we ought to consider the volumes of spheres with Megalithic dimensions in addition to the cubes and a 6 Megalithic Inch sphere held a litre and a 1.5 MY wide sphere of water weighs a metric tonne. The level of accuracy was not spot on, but at a level of 99% fit we were surprised to put it mildly.
We are used to modern measurements that are ad hock but the 366 system works in depth. Take just two examples:
1. Earth mass
 One Megalithic degree (366^{th)} slice of the Earth = 360 x 10^{20} pounds
 One Megalithic minute slice of the Earth = 6 x 10^{20} pounds
 One Megalithic second slice of the Earth = 10^{20} pounds
2. Temperature (hypothetical scale)
 Water freezes @ 0 degrees
 Water boils @ 366 degrees
 Absolute zero @ 1,000 degrees
