Are you telling me that these extremely different environments all suddenly (the blink of an eye in evolutionary terms) created the same population pressures that forced/pushed the development of agriculture, permanent settlement and civilization across the world?
Er, well, ice ages tend to be global phenomena, so, yes. No indication of "forced", by the way - just enabled.

But then again they are dated with the same methods that confuse recent murder victims with ancient skeletons. As I said earlier radiocarbon dating and other methods from that group rely on relative rather than absolute dating - much of it lies in the interpretation and that's why I'm disagreeing with.
Laughably false in every respect.

how you reconcile the sudden advent of civilization across the world with the slow, gradual, hundreds-of-thousands-of-years evolutionary approach.
Not only are you misapplying a principle, but you are misunderstanding the basic nature of gradualist/Darwinian evolutionary theory. "Gradual" just means as opposed to saltational or punctuated. The movement of a car across a highway is gradual, yet its speed may range from 0 to 100 k/h at any given time or in any given interval.
