You can fly a rocket in a circle around the northpole and it would appear as you describe.
But I just told you that we launched it in just one direction and that we can observe with the sensors onboard that it goes in a straight line... When we send rockets into geosynchronous orbit, it travels along the equator and only to the west, never making any turns, and still comes back.
You also need to explain why it obtains a higher speed when you launch it to the west along the equator than if you launch it to the East. Which is why all launch pads for launches to that orbit are kept close to the equator (like KSC in Florida for American launches, or Guiana Space Centre in French Guiana for European Launches).
You can't explain it because it 100% proves that the Earth is indeed a globe.
Please tell me why these ground stations can only communicate with flying objects when they are within a specific radius and why that radius increases the higher the object is above the ground.
That makes zero sense with a flat Earth model of the Earth. And is a complete debunking of the model.
Now tell me instead why we can do the math to show that the ratio at which an increase in the height of the object and the radius at which it can be detected by a given ground stations scales perfectly with the rate at which the Earth curves. I'm looking forward to your reply.
