I don't know, just more stuff than less stuff is better. Flat earth sounds like all you have to do is find proper relative motion in a system and make all the stars or planets follow a motion Like how they had the geocentric model before heliocentrism.
Space is infinite and full of life in the form of corals and plants. I believe there's planets like ours where the sunset shines a different hue, or you might even get two sun sets. Imagine a nightsky with a few planet like moons. Or a night sky with a neighboring ring galaxy
