See thats a terrible argument. If you cant make a diagram that accurately represents the spherical models claims then why would i pretend you understand it well enough to refute it. Again, youre diagram does a far more poor job explaining the presence of seasons than the spherical model. The image of spherical earth in your diagram is the peak of summer in the norther hemisphere, when the "north" point on the axis of rotation is closest to the sun causing the closest point to the sun to be north of the equator. What season is it in the lower image? How would seasons even happen according to the lower image?
