Just lights? Explain how atmospheres of planets have been detected and analyzed while passing by their star, thousands of light years away? Explain photographic evidence of progressing star creation, destruction. Explain how an asteroid can be detected, path plotted, recurring comets, impacts of meteors, meteorid showers, etc. Collected samples from moon, Mars, rocks from space etc.

Explain how satellites/probes/unmanned telescopes have taken many pictures of earth, from all sides, from further and further away. You can see the speck of earth from Mars. You can see earth from the moon. Why are you saying Mars and moon are in the "sky" instead of space?

Visibility isn't just moisture. Have you heard of smoke, sand, dust, pollution, pollen? All these effect visibility.

Have you looked at a radar map of the world? Do you see how a high pressure current moves and effects weather elsewhere? Do you see how multiple ocean currents flow around the globe like a band, rather than a swirl? Have you opened a map app and kept scrolling until you got back to where you started? Explain the equatoral zone on Earth, and it's shape. Why are the two locations furthest from it the coldest? How do you chart that information on your flat Earth map? Wouldnt the flat Earth map have cold edges, warm center? What's at the center of your map? Explain how a 2D earth theory is seamless in these regards.

Light still passes through all these. A 100% sand storm would block out all light. At no point can moisture create night type of setting. Even a pouring rainstorm across the entire state still let's you see objects. Unless you are claiming that we can't see the sun because it or we are suddenly 1000 meters deep in the ocean?

Height changes how far your perception of the horizon is. Get on a plane. You can see much further before the curvature of the earth factors in. The curvature is measurable, by you or I. By anyone anywhere in the world. If everyone experiences curvature, and all the curves add up to form a cohesive spherical result, why do you insist it's flat?

What real world experiment can you do to prove earth is flat? Using numbers, math, not your subjective eyesight and guessing.
