If Oumuamua is a derelict space craft then what happened? Was it in a battle and the crew killed or did the life support fail? Maybe there's a protocol for dealing with old craft. They could sell/trade them, maroon them on a planet or send them into a star. To just let them wander creation for billions of years seems odd. There's a rumored space craft graveyard on the moon and in Siberia.
