If religion is a product of contemporary society and circumstances, and not from some sovereign source, it’s fun to speculate on what social values might emerge later and what religious views might result.
Something I see for our entire global community is a realization the forces of nature are finite entities. That is, a realization man’s activities affect the global environment and the globe’s ability to support humans is not infinite.
While environment is a concept from science, I think there will be always people who are drawn to the ceremony and mysticism of the spiritual world. When the focus of ordinary people goes from thunder and lightening in the sky to the ability of dirt to produce enough food, why would we not see the spiritual world moving from the sky, where is has resided in some cultures, to the earth?
The religion that preceded Judaism and Christianity, was about the earth. Pagans must have been originally hunters and gathers that preceded domestication of animals and crops.
Wicca, the modern version of Paganism, has an earth focus. While Wicca is not popular now, I could see it, or something becoming popular.
It would start to grow from a population of nonspiritual people, such as the group growing today. Popular culture’s focus on a precarious environment would catch this group’s interest and Wicca would provide the spiritual dimension.
If religions were traded on the stock market, I’d buy Wicca.
