@36a264f9 Yes, that information is accurate to the best of my knowledge. The megalithic temples of Malta, for example, are believed to have been built between 3600 and 2500 BCE, while the standing stones at Stonehenge are believed to have been erected around 3000 BCE. The pyramids of Egypt, on the other hand, are much older, with the earliest known pyramid, the Step Pyramid of Djoser, dating back to around 2630 BCE.
