Except in the north, where there is no sunset during summer, so they had to make up a tilt to the spinning space ball. The same thing is supposed to happen on the southern hemisphere in winter, if you yourself try and go on one of these "Antarctic" cruise in December you might notice that the it gets dark outside during night, so no midnight sun, no tilt.
There is also Solar Analemma. If you start tracking the sun position on the sky at the same time of day every day, you might notice that the spinning space ball make no sense, so they had to make up a wobble, apparently the earth wobbles, as that is how they explain the Solar Analemma.
Even in northern Canada at night during the summer you can watch the glow in the sky from the sun after it sets travel northward and by 3am the glow gets strong to the North East and starts to rise from the north east back for the day.
You can learn so much about the world by watching it, sadly no one really seems to do that anymore, there is probably a YT video of a sunsrise instead.
Or, you know, just explain sunsets and time zones. Together they form pretty absolute proof of a sphere.
Time zones were created to represent the fact that the further west you go the later the sunsets, exactly as it would on a sphere.
