There's no external evidence for the basis of the world's religions. God didn't make the world in seven days, evolution is an observed fact, Coyote isn't the "trickster", and there's no evidence for transmigration of souls, not when the personality is inextricably linked to the physical and chemical structure of the brain housing it.
But....the human mind is certainly well known for it's ability to believe things that aren't true to explain things that aren't clearly understood. That's were religion comes from.
The best world is the world were religion is recognized as a mental disorder and those suffering from it are provided with assistance to recover from it, not encouraged to practice it.
