During this time various cremated people were buried around and in these stone holes.
A second, small circle of bluestones (called by the excavators ‘bluestonehenge’) was put up around the same time a little way to the east, by the River Avon.
When something dies the carbon it contains decays gradually over time.
Radiocarbon dating measures the amount of radioactive carbon remaining in an archaeological sample.
The archaeologists used a variety of techniques, including radiocarbon dating on workers' campfires from millennia ago, to discover that holes cut into rocky outcrops to gather the stones were made centuries before Stonehenge was built.
that the "first Stonehenge" was in Wales and "what we're seeing at Stonehenge [in Wiltshire] is a second-hand monument." He added: "Normally we don't get to make that many fantastic discoveries, but this is one." The discovery may provide a strong new theory for where the monument came from, but it's one of many out there, some of which are more rational than others.
All living things contain carbon, including a naturally radioactive form of carbon.Large "Station Stones" are aligned in the direction of the northernmost moonset and the southernmost moonrise.According the English Heritage Organization, the first stage of construction was just a circle of heavy timbers surrounded by a ditch and an earthen bank.On the more conspiracy-theory end of the spectrum, some people believe that the Nephilim, a race of giants who were almost totally wiped out by Noah's flood, used their greater height and strength to help build Stonehenge.from the 1100s, a giant is shown helping Merlin construct the monument.At the time of Stonehenge's creation, the wheel had not even been built - modern tests have shown it is possible to move stones of similar size on rolling logs or sleighs, but the most archaeologists can do is make an educated guess.
