re: Rule Oceania
If you are an intelligent being with manipulative appendages (think crabs or
octopi) living in an ocean environment with all its abundant resources, one
may have more choices and possibilities for development than it might appear
to us.
Who knows, maybe some intelligent squid on a water world think that creatures
living on land would be ill-suited for spaceflight as they are not used to being
in buoyant conditions, plus they have to work so hard to get their resources.
