There are substantial grounds to claim that the most significant archaeological discovery of the 21st century is the Göbeklitepe.
First of all, it dates back to 12 thousand years ago. In other words, it’s approximately 8 thousand years older than the pyramids and 7 thousand years older than the Stonehenge. Furthermore, it is even older than the human transition to settled life.
Therefore, contrary to the widely held view, it proves the existence of religious beliefs prior to the establishment of the first cities.
