Where did the aliens who built Nan Madol came from?...
or perhaps somewhere in the idontgiveafuk galaxy in the heapofallshit systems is a micronesian clan, who's ancient ancestor Pulalap couldn't bear to see the aliens go back home without them.
perhaps one day they will try to contact us and tell us all about it.
One day the Israelis and Egyptians are going to stake their claim on Nan Madol.
Okay, let's all just admit that the Marshallese built it after they conquered all of micronesia.
