if ya ask me modern man has religion. early man had life
how abut the statues found in Europe, made over 5000 years ago. the symbolized a fat woman. At that time if you were fat it was a sign of wealth. and it still is in many developing countries. And then the Iron age cultures in northern and central Europe, where the sacrificed men and women and animals etc and then "dumped" them in a bog. Bogs or swamps as you may call them were believed to be a passage to the spiritual world. and oh yeah, they were BIG at that time. National geographic just had an article about the bodies found inside the bogs. you guys should definitely check it out.
and then for example lakota cultures had religion.
The heathens of finland also had religion which is referred on this poll here:
