Best globe earth proofs, off the top of my head, in no particular order:

Ships disappearing over the horizon from the bottom up not just getting smaller until you can’t see them anymore. (Same for mountains or any distant tall object).

The mathematics of navigating using the stars and a sextant that work in the real world but would not work if we were not on a globe.

Plane flight paths which follow an apparently curved route but when mapped on a globe is a straight line. (And no I don’t believe all the private aviation companies in the world are somehow in on the conspiracy.)

A laser beam projected out level to the ground does not stay level but appears to rise at exactly the rate predicted if we were on a globe with a circumference the same as that which we have calculated for the earth.

Our model of the earth which can explain how it formed and what its structure is which is supported by P and S waves from earthquakes.

Constellations getting lower in the sky as you travel south in the northern hemisphere and or as you travel north in the southern hemisphere.

The fact that different constellations are visible in the northern and southern hemisphere.
