One planet, one religion
Let's imagine that there are numerous planets within the same solar system capable of supporting life. People residing on these planets cannot meet each other.
On each planet there is only single religion that isn't challenged by anybody, so entire world is practising practising Jew or practising Hindu or whatever.
Which planet would you rather live on had you the opportunity to chose where you'd like to be born? Keeping the similarities between the religions (as we know that many influenced each other), but imagining that they do not know of the other religions and they'd probably never find out, which planet do you think would be best run? Why?
What would be your order of preference be, starting with the planet you'd most like to live on and finishing with the planet you'd least like to live on.
I didn't include the religion list, as you can add any religion you'd like, including ancient religions as well as new age. Confucianism, although a philosophy, can be counted as religion too.
