If earth was flat, then the shape of the earth’s shadow cast upon the moon during a lunar eclipse would be subject to perspective depending the location of the moon relative to the flat earth. So the shadow should be rounder if the eclipse occurs midnight, and would be more of a narrow ellipse if the eclipse occurs just after sun set or just before sun rise.
Yet the shape of the shadow is manifestly the same no matter what part of the night the eclipse occurs. Such a shadow can only be cast by a spherical earth.
