Probably a superpowers born type of world, I'll give them enough time to advance their technology enough to beware of external threats and chuck a few radioactive Mar's size meteorites at them, far enough for them to choose what to do and how to reacts about it.
If they starts killing each other for survival, I'll have a good show before obliterate them. If they choose to unite and lives, I'll leave them alone for a few centuries.
Either ways, I'll make a new world and restart the cycle, before you questioning what I'm talking about, 1. I don't know either and 2. I'm supposed to be a god so I may as well act like one :3
