But in such a world, everything would be different. One less rhyme for June. Navigation & astronomy would have developed differently and influenced politics in different ways. Places where you could see the ring edge-on would be special. Would we have space flight?
One thing I ask. Don't mention the ring. Every book that has ever been written about life on earth assumes the moon, whether it is mentioned or not. So this new book need not mention the ring explicitly. It should just assume it's there.
