Common wisdom says there are about 6,000 stars visible with the naked eye on earth. Of course, half of them are below the horizon. Of the 3,000 stars above the horizon, 500 of those too close to the edge, or obstructed. That leaves about 2,500 visible stars on a clear, dark night.
There are 4,200 religions in the world.
That means that there are more religions in the world than there are stars you can see on a clear night.
