Avebury is a quite remarkable megalithic monument set in the Wiltshire countryside. The village of Avebury contains ancient stones which comprise two interior stone circles, the North Circle containing 'The Cove' and the South Circle, are perhaps indicative of a binary solution to our solar system. This ancient site is perhaps a representation of what was being observed in the skies at the time.
The above illustrations are taken from page 22 ‘Mysterious Britain’ by Janet & Colin Bord; Paladin Books © 1976 The Authors say that this is possibly how Avebury looked some 5,000 years ago when it was first erected as a Sun Temple, if this was a sun temple then why are there two circles. The two stone patterns are identical to each other so perhaps the ancients of Avebury ‘documented’ the passage of Nibiru by showing two Suns!"
Indeed the first settlers in the Avebury area, specifically at Windmill Hill, are traced to 3700BC, which is approximately the time of the Anu's return to Earth, highlighted as 3760BC by Zecharia Sitchin . So it appears this is tied in with the return of Nibiru to the same period. So it is conceivable that the people who settled in the Avebury area and began to plan the stone circles there had witnessed a most remarkable celestial phenomenon; the return of the Dark Star, the Sun's binary companion. One can imagine how such an event would have captured their collective imagination and driven them to plan the great circles that arose over the next few centuries. (Dark Star)
