If you were going to populate a planet with a society with no cultural or historical baggage of their own, what would you have them learn? What would you give them to start with. What books, information, knowledge, etc.
The goal would be to have a peaceful, healthy, sustainable society. They would be as isolated on this planet as we are on ours. We would not be able to interfere with them ever again after starting the evolution process. They would not have to worry about outside invaders. The information you give them would be magically ingrained in the adults so that we don’t have to deal with them finding a library and wondering where it came from.
The question at hand is what information would you supply, not how would this experiment be actually accomplished.
