Would you be considered a 'just' and 'reasonable god'? Perhaps your world would be void of intelligent life. What sort of ecosystems would your world support? Would it be round? Flat? One dimensional? Multi-dimensional? In another Universe? An alternate Earth? Would your fictional world have different laws of physics?
Binary star systems are not rare. Many star systems have two suns that orbit each other. Finding a star system with more than one planet was first announced in 2012. Kepler 47 is the first star system discovered with circumbinary planets. NASA's Kepler is a rich resource of ideas for fictional world builders.
