But you can't deny the truth light warps around a sphere especially one with with an ozone layer like our earth would cause the light to not even hit our earth. But a flat disc would absorb all of the light
The moon shows slightly more or less of the far side during the lunar cycles. If you actually observe it, parts of the moon that aren't visible at some points become visible during it's transit across the sky. This is only possible if it is a sphere. @RidleyChozo
