Earth's distance to the sun is based upon assumptions.
Logic dictates the earth is far closer to us than we're lead to believe. The original experiment 'proving' the globe relied on parallel sun-rays.
Anyone who has ever been outside to see sunlight shining through clouds would notice that rays of sunlight are certainly not always parallel to one another.
Does one light on the ceiling of a gymnasium light it entirely? The sun rotates above the earth, lighting it locally rather than globally.
No, but since the gym floor is flat, even if a single light doesn’t illuminate the whole space, I can still see the light on the ceiling. If the sun is up above the surface of the flat earth, lighting locally, why can’t I see it all the time? how does the sun rise and set at the horizon in a flat earth?
Sure, that was just a relatable demonstration of how light doesn't necessarily illuminate an entire unobstructed area.
The reason you can't see the sun at all times is related to rules of perspective.
Everything as it moves farther away from you moves towards your 'apparent horizon'. A road on flat ground, as distance increases, moves up towards the horizon. A cloud, as distance increases, moves down towards the horizon.
Ultimately what that means is, there's exponentially more 'stuff' in the path of light near the horizon. So as the sun moves away from you, it also moves behind anything that is in-between your viewing angle and the sun. So that's clouds, mountains, buildings, or even just particles in the atmosphere itself.
If you own a drone, you can test this yourself. You can set an altitude on your drone over your head - then fly it 100 feet out in front of you at the same altitude. What's happened to your viewing angle? That change continues as you add distance, until the object is nearly sitting on top of the horizon itself.
So the short version is, the sun moves away from your location. As it moves away it also moves towards the horizon due the rules of perspective that you can test literally anywhere. Once it's far enough away, there is enough 'stuff' in between you and the sun at your viewing angle for it to disappear from view. As that happens, the sun appears to set behind whatever that stuff is. Usually clouds, mountains, trees, nearby buildings.
I see what you mean but I don’t really grasp how that gets to a point below the horizon entirely. Getting “closer” to the horizon makes sense, but not below
Also, what causes the change in length of time to experience daylight?
It sounds like you are understanding exactly right. The sun will never go below the horizon. It will be blocked by all of the 'stuff' that has also made it's way to that level of your apparent horizon. Imagine 250 miles of clouds also collecting at the horizon. It would create a wall of clouds, ultimately. Even atmosphere will do this. I think you get the gist.
Change in daytime - The sun's position changes over time. You can google Gleason's flat earth map to see a general representation of how things are oriented. Now imagine a sun spiraling around the north pole's center, slowly creeping inward, reaching the tropic of cancer and then slowly spiraling outward to the other tropic. The sun's bias north or south of the equator still dictates the length of daylight.
Let me know if that makes it possible to visualize.
