I mean more something like: when did the first civilizations started to appear? 1000 years, 5000 years, 10 000 years?

I like the idea of wip threads, I never said otherwise. I also believe that worldbuilding and mapping does not need to be done by the same person. A lot of mapper are really bad when it comes to populating places. And a lot of world builder can't make maps or don't have the time to do it.
