One have you ever tried to watch at Mars with an amateur telescope? Focus what? Second. Read this at least. https://royalsocietypublishing.org/doi/10.1098/rspa.2019.0680 set up an experiment and tell me how your results contradict the theory of a ball rotating earth.

Plus novacula Occami .... Every single liquid when not exposed to external forces turns into an almost spherical shape due to the internal coesion forces that on the scale of a planet are mostly gravity. So why should this planet that obviously is hot and melted how we can see from volcanoes and temperature gradient when you go deep, decide to turn into a flat surface? How gravity points down in on the border of the supposed plane the majority of mass is sideways? Why if every body we can see in the sky with enough definition is a sphere? How radio waves that get reflected by ionosphere sometimes go around the planet doing an echo with a timing that is consistent with the radius of the planet? And so on. Ditch the internet that lies and put your hands in real science. Real science=doing reproducible experiment.
