Do you sense the sacred on the shores of the ocean or the banks of a river? Do you see the divine in the craggy slopes of a mountain or under the light of the midnight moon?
Reverence for and worship of nature is humanity's oldest religion, from a time before that word even existed. Humanity saw Gods and Goddesses and spirits and Powers in the trees and the rivers, in the vastness of the sky and the ocean, in the tiniest buds and blooms. We don't know what the earliest humans called their Gods and the spirits of the natural world, but we do know the terms and titles used by the ancient Greeks; terms that are still used by their spiritual descendants today.
