Simple answer:
.
All the flat-earthers have to do is address each point in turn. But they won't because they can't.
.
Why can't they?
.
Because:
.
There never has been and there never will be any depiction of a Theodolite shooting a level line of sight from a promontory of even a few hundred feet toward the horizon which shows the horizon "rising to the level of the viewer" as flat-earthers keep chanting without any evidence.
.
There never has been and there never will be an intelligible explanation for why the full moon faces with its sun-illuminated face toward the earth from high in the sky, from the flat-earth hypothesis which places the sun above a "flat" disc earth at nearly 90 degrees to the line of the moon's light as viewed from anywhere on planet earth.
.
There never has been and there never will be any "flat" earth plausible geometry describing how a quarter moon makes the angle it does to the sun (while insisting it and the moon are some 3 thousand miles above the earth) twice each month for all to see.
.
There never has been and there never will be any reasonable excuse for the fact that a ship or plane traveling due east (or due west) along the equator does not have to turn right (starboard) or left (port) in order to remain on the equator and due east (or west as the case may be).
.
There never has been and there never will be any "flat" earth demonstration of WHY two parallel courses once embarked will in due time collide with each other on the real earth, since they don't do that on the "flat" earth model.
.
There never has been and there never will be any reasonable "flat" earth explanation for how any weighted object in a vacuum will consistently be pulled in a perpendicular direction from the horizon line regardless of where on the real earth the experiment is conducted.
.
There never has been and there never will be an explanation for the numerous flights of aircraft that pass over or close to Antarctica and traverse a distance too short to be plotted on a "flat" earth model, when many pilots, co-pilots and navigators who routinely fly such courses have and will continue to attest.
.
There never has been and there never will be any honest video showing the horizon unable to conceal distant objects beyond the curvature of the earth, even while the refraction of light through the water vapor above a body of water makes it appear otherwise, since the progressive foreshortening of such objects belies the distortion caused by the refraction.
.
There never has been and there never will be a seagoing navigator using a sextant and sea charts who can accurately plot his course over a great distance overseas, when he presumes the earth is "flat."
.
I can go on.............
.

.
There is plenty more where that came from.
.
Funny nobody who supports flat-earthism has any argument or substantive response -- just frustration.
.
It's okay to be frustrated! Being a flat-earther means living with self-contradiction day in and day out.
.
You must enjoy frustration, though. That part doesn't add up.

I see.  So you don't think that Flat Earth can predict Eclipses.  I don't know why you think that, but I think you are misinformed.  Flat Earth models can predict Eclipses and have done so for thousands of years.  



Total Eclipse of the Mind, by Eric Dubay

Now, that also the earth taken as a whole is sensibly spherical, we could most likely think out in this way. For again it is possible to see that the sun and moon and the other stars do not rise and set at the same time for every observer on the earth, but always earlier for those living towards the orient and later for those living towards the occident. For we find that the phenomena of eclipses taking place at the same time, especially those of the moon, are not recorded at the same hours for everyone that is, relatively to equal intervals of time from noon; but we always find later hours recorded for observers towards the orient than for those towards the occident. And since the differences in the hours is found to be proportional to the distances between the places, one would reasonably suppose the surface of the earth spherical, with the result that the general uniformity of curvature would assure every part's covering those following it proportionately. But this would not happen if the figure were any other, as can be seen from the following considerations.

For, if it were concave, the rising stars would appear first to people towards the occident; and if it were flat, the stars would rise and set for all people together and at the same time; and if it were a pyramid, a cube, or any other polygonal figure, they would again appear at the same time for all observers on the same straight line. But none of these things appears to happen. It is further clear that it could not be cylindrical with the curved surface turned to the risings and settings and the plane bases to the poles of the universe, which some think more plausible. For then never would any of the stars be always visible to any of the inhabitants of the curved surface, but either all the stars would both rise and set for observers or the same stars for an equal distance from either of the poles would always be invisible to all observers. Yet the more we advance towards the north pole, the more the southern stars are hidden and the northern stars appear. So it is clear that here the curvature of the earth covering parts uniformly in oblique directions proves its spherical form on every side. Again, whenever we sail towards mountains or any high places from whatever angle and in whatever direction, we see their bulk little by little increasing as if they were arising from the sea, whereas before they seemed submerged because of the curvature of the water's surface.

Ptolemy very clearly taught that the earth is a sphere, the central one in a series of concentric spheres which moved the stars, moon, planets, and sun.  The Amagest includes his proof of the spherical earth

I got 30 seconds in and he had already said something that so completely destroyed his credibility there was no point continuing.

He started of by claiming that Copernicus introduced the ball earth and that Ptolemy's model (which did in fact predict eclipses and moon phases) was a flat earth model.  He uses this absolute falsehood to counter the position that there are no flat earth models that can predict eclipses, etc.

Ptolemy wrote this in the second century and it became the dominant model in the West, including Christendom throughout the middle ages.  It began to be challenged with the introduction of the Copernican model, but the majority of scientists (and the Church) sided with the Ptolemaic until the introduction of Newtonian physics made a heliocentric model more plausible.

An interesting side-note: St. Robert Bellarmine, had an interest in astronomy.  Early in his career, in his "Louvain lectures" he challenged the Ptolemaic model with the idea that the heavenly bodies were not moved by spheres but by some other means.  (He did not challenge the idea the earth is a sphere, of course.)  It is interesting that he is often portrayed as anti-science, when he was in fact at the cutting edge of it.

Anyhow, can anybody produce a genuine flat earth model that predicts eclipses?
