A flat earth would be quite comfortable to live in. Picture gardens, lakes, ponds, pathways, wandering sheep, rice paddies. Trees would be okay as long as they weren’t too large - no giant Sequoias that might upset the balance and cause the earth to tilt. No huge oceans with giant waves to bring harm and destruction or to get lost in. Hills and mountains, especially high jagged peaks would add interest but would also complicate things: they would have to be climbed, they could perhaps be hidden in, and they cast huge shadows. There is serenity in sameness. A flat earth would be quite safe and comforting. But then someone would probably come along and tell us that not only is the earth round, it spins and orbits! What a dizzying thought!
