The sextant measures angles on a plane, the angular size of the Sun is 32 minutes and the definition of a mile is 1 minute. This is not proof that can be refuted by an inconclusive youtube video of a rusty ship wreck, it's direct measurement.
You don't understand how the sextant works.
To you, everything in the sky is xx miles wide - even though a "mile" is a made up human measurement.
