Yes, some 9100 years prior to Christ... very long ago.
What is amazing to me is that they were able to do this so long ago, just barely after coming out of the hunter/gatherer stage of things (about 1000 years earlier??). Although I suppose with the growing of crops, the knowledge of seasons and time became much more important to them.
BTW - all of this development (agriculture, communities, large structures, etc.) was possible due to Global Warming.
