You don’t think a function of the temperature from the sun to the earth forms a continuous line? You think it’s piecewise? It’s continuous! Yeah it probably bottoms out to effectively zero pretty quick, but there’s some distance from the sun that would be the right temperature. Sure, the other rays from the sun might not make it livable. Sure, it might be so narrow there’s no way to effectively keep yourself in orbit there without getting sucked closer and burning up. Sure, it’s a dumb thought experiment, but there’s no way there isn’t some point where it’s comfortable.
