Can the story of Adam and Eve be evidence of human behavior modernity?

Think about it, human beings have been around for 200,000 years but we only reached behavior modernity (i.e. culture, civilization, etc.) around 50,000 years back.....Which means that for 150,000 years we have been hunter-gatherers that have probably very limited to none (assumed) cultural creativity or expressive thought. This is the state that Adam and Eve lived in during their time in Eden, since they didn't possess the "the forbidden knowledge of God" or whatever, and lived off the fruits of the plants. After we achieved behavior modernity we achieved "God-like" knowledge (i.e. civilization, agriculture) it would have been impossible to revert back to a primitive hunter-gatherer (hence, why Adam and Eve were cast out of Eden). As a creation story, perhaps the story of Eden has roots to the point in paleontology in which humans have achieved behavior modernity.
