At https://phys.org/news/2025-06-precise-dating-carnac-megalithic-monuments.html… some might like to question how reliable the actual dating is but that is not necessary something to worry about too much as it allows the archaeologists to plot the erection of the stones on the mainstream dating calendar. Compare it to the geological column. Geologists have a calendar in which they can compartmentalise the various layers unearthed during research. It seems to work. Actual time and dates are not relevant when you think in terms of millions of years – or in thousands of years. It is the position that is alloted to the findings that counts. Dates have been pushed back consistently as C14 becomes more and more counterbalanced with other dating mechanisms, producing a Bayesian construct that is useful for the professionals. Don’t dismiss the findings because you don’t like the dates. At the moment there is no sign mainstream will return to just a C14 and tree ring chronology set up. You have to accept the revised dates and rearrange your brain so that 3200BC becomes 3500BC – and so on.
The Carnac stone rows are a dense collection of megalithic sites in Brittany. There are a lot of stone rows. Now, several of these stone rows have been dated between 4600 and 4300BC. These dates cluster close to a major upheaval in the natural world – that set in motion widespread migrations. Especially in Europe. For instance, in its wake early farmers arrived in Britain. What we may ask – were the stone rows, or the first batch of them, set up to look at what was happening in the sky? Leading up to the upheaval – or in its aftermath.
At https://phys.org/news/2025-06-ancient-canoe-replica-paleolithic-migration.html … researchers in Japan and Taiwan have simulated suspected methods Palaeolithic people used to move around in East Asia. They recreated ancient tools in which to fashion a dug out canoe and then made the journey they think occurred 30,000 years ago, between Taiwan and the islands south of Japan, such as Okinawa. It meant crossing the Kiroshio Current which could have seriously caused problems for such a flimsy craft. They paddled the 225 km separating Taiwan from the Yonguni Islands and it took 45 hours. They arrived, elated. Thereby proving it was possible – by the remote ancestors of the Polynesians.
