I have been having a recurring thought for many years now. Many prehistoric carvings and statues found are of what can only be described as pregnant women. Why the focus on pregnancy? Were pregnant women held in high esteem because getting pregnant and going full term with a surviving infant and mother was uncommon?
Many of the prehistoric peoples seemed to focus on worshipping a fertility goddess. Worship of actual humans and the events surrounding them that eventually turned from physical to spiritual. Could this be where religion stems from?
