World Religious Population

When Nietzsche declared “God is dead” he meant that Judeo- Christianity has been lost as a guiding force in our lives and there is nothing to replace it. Science pushed God off to the sidelines and took over the reigns yet I believe there is still a strong religious contingent still at work out there. With approximately 6.8 billion people on the planet approximately 6 billion are of some faith that is about 90% of the planet! World Religions
