hold both beliefs globe and flat for hundreds of years.
you can "believe" whatever you want ... :)
Just like "flat earthers" can believe whatever they want, but the internet will still works for them - even though the internet was built with "science".
Man watch some celestial navigation videos, you have it completely inverted. How do I know? Cause I've been a licensed mariner my entire adult life. When you use a sextant you view a local apparent horizon, and the zenith is straight overhead. You have to correct your observation to get a celestial horizon. This forms a 90° angle (flat earth horizon) which you use to calculate the local apparent altitude of a star.
Whether you are on a globe or a plane you would still have to make corrections to form a 90° angle with the celestial horizon and zenith. If you are on a flat earth it's because of your height of eye over the ocean and potential atmospheric distortion. If you are on a globe it's also because of earth curve. BUT EARTH CURVE IS NEVER INCLUDED IN CELESTIAL NAVIGATION CALCULATIONS. Your corrections assume a plane dipshit.
The sextant wasn't invented until like 2000 years after Aristotle. I think what you are referring to is the Eratosthenes experiment with pillars and shadows in two different cities that 'proved' a sphere. Unfortunately you can produce the same results on a plane with a local light. I can show you with two beer bottles and a light bulb, so this effect fits the flat earth model.
It was literally geometry that first clued me in to flat earth. As a Mariner I would sometimes do earth curve calculations to see when an object like a lighthouse or drilling rig should come into view. And I kept seeing them so far off, with such clarity that refraction couldn't explain it. It was as if there was no curve that you would expect on a planet of 24,901 miles in circumference. Then finding out nasa fakes everything finally got me to investigate flat earth.

let me restate:
the sextant uses geometry (which Aristotle used to "prove" a globe, but whatever)
i thought flat earthers didn't believe in geometry.
am i wrong about that ?

sorry my point is that the sextant relies on geometry - which Aristotle (eventually) uses to "prove" Earth is a globe.
you don't really believe in all that geometry brainwashing do you ??
