I have watched many Flat Earth documentaries with an open mind. What Flat Earthers have done really well, is document Nasa's lies. The augmented reality tricks, the "space walks" under water, etc.

But the presentation of the Flat Earth theory vs. Globe Earth theory is just not done well. The Globe Earth explains basically everything really well, like the movement of the sun, the moon and the stars, timezones, etc.

Flat Earth gives a very unconvincing explanation of the movement of the sun for instance. If someone is proposing a better model, the better model should have better explanations for phenomena that are observed, not worse explanations.
