In Scotland pits were found, whose age is more than 10 thousand years. According to the researchers initially in deepening were inserted pillars that allowed ancient hunters and gatherers to determine the moon phase and count the months. Scientists make the assumption that it was the Ancient calendar. If their approval is confirmed, this calendar will be the most ancient on the planet Earth. Until then, those were considered Mesopotamian bronze calendar.
Scientists have found that the pits were dug in a certain sequence, and then inserted the poles. Over time, the pit is constantly updated, and the pillars and standing stones, which were based, were periodically replaced with new ones. This is the reason, which gives scientists the ability to determine the time period of the historical findings.
Initially, the presence of unusual pits were recorded during aerial surveys. The place has interested scientists-archaeologists who began excavations. By their remains, scientists have determined the age of the calendar, and were amazed that he is 5 thousand years older now known Mesopotamian.
After the discovery of the calendar, scientists have wondered why in the stone age needed a calendar? Supposedly, one pit was divided into three weeks, the orientation to the East was allowed to make adjustments and keep track of time.
