There is no convincing them through any kind of logic or observation. The logical proof of the shape and size of the earth is remarkably simple and straightforward, with math any trigonometry or geometry student could prove on their own. Eratosthenes did it a few thousand years ago with observations from a deep well and the shadow of a vertical rod a significant and measureable distance apart on the same day at the same time. These are simple and direct observations that anyone could make and repeat themselves. If Eratosthenes proof isn’t clear enough to them, nothing will be.

There was even a documentary in which self professed flat-earthers performed a variation of this experiment with some careful arrangement of a laser over a large lake. Unsurprisingly, they did measure the curvature of the earth (with much less precision than Eratosthenes), but they still couldn’t accept the results.
