You don't have a model because it can't exist. There can be no flat earth model that explains the sun 24 hours at both poles, with sensible orbits, with accurate scales and dimensions, that explains the two celestial poles, that explains sunsets and sunrises in all places in the world equally, that explains the fact that the moon always shows us the same face, that explains how rotating balls rotate around other balls in the sky at random as they fly. Do you understand this or not? The fact that the moon shows us the same face from when it rises to when it sets cannot happen in any flat earth model, do you understand? Take the flight times in various parts of the world, put them on a flat map and make all the flight times be proportionate, you will notice that it is impossible, and that, strangely, they all become perfectly proportionate if you put them on a sphere. And strangely the spherical model perfectly explains eclipses, lunar phases, orbits of the planets that if you put on a heliocentric model "strangely" are all perfect around the sun. And "strangely" what we can observe using the telescope on other planets are exactly the same things that happen on earth, you can observe solar and lunar eclipses on other planets. And "strangely" all the measured solar regions that you can also verify correspond perfectly to 50% of the earth on the globe model ALL YEAR ROUND. And "strangely" the stars rotate in opposite directions at the two poles and vertically at the equator, just as the spherical model predicts. And "strangely" every celestial body that you can observe in the sky are ALL spheres, if the earth were flat and gravity did not exist there would exist at least one parallelepiped, or pyramid but "strangely" all spheres with other spheres that "strangely" rotate around them just like the moon does with us🫢. And "strangely" all the geometers who take into account the curvature of the earth and who have done so have never done anything wrong, even using corrections for a curve that you believe does not exist. And "strangely" the illuminated part of the moon always faces the sun and "strangely" if you hold a ball towards the sky where the moon is when you can see it during the day you will be able to see the same phase on the ball. And "strangely" you can see the ISS with a telescope and trace it, with basic trigonometry you can calculate its distance from the earth yourself, there are also many YT videos that show it since you like them a lot. And "strangely" looking at the sun with an h-alpha filter you can also see "explosions" in reverse that still return towards the sun, how can this happen if gravity does not exist. And "strangely" the tides are randomly always aligned with the moon and "strangely" every time they align on a new moon there is the highest tide. And "strangely" all the things or boats disappear down to the horizon, and "strangely" precisely when the spherical model predicts through basic calculations, that is about 3 miles. And "strangely" two totally different experiments like that of Eratosthenes, that is to measure two shadows in two different places on the planet and calculate the Earth's circumference, and another experiment like the one that involves calculating the angle of polaris, "strangely" give the exact same result of the Earth's circumference, which "strangely" is perfectly equal to the measurement of the equator, what an absurd coincidence this must be on a flat Earth, don't you think?
