I would say Epicuris was intellectually fulfilled. As was Democritus, Anaximander and many other Greek philosophers who were atheists who knew nothing of evolutionary theory.Sorry intellectual fulfilled atheists can not exist without evolution.
Throughout history Atheists have been able to reject the God concept based simply on lack of evidence for such a being. Evolutionary thought need not enter the picture.
While today, if you asked an Atheist where the diversity of life came from, they would answer with the logical scientific answer of Evolution, it is not a prerequisite for non-belief in any sort of deity to have a working knowledge of Evolution and Evolutionary Theory.
