‘Flat’ and ‘Level can mean approximately the same thing in everyday conversation. But in the context of science and engineering, they have different meanings. ‘Flat’ describes a planar surface. ‘Level’ means at the same height or perpendicular to the direction of Earth’s gravity.
Flat-Earthers interpret the word ‘level’ as if it always has the same meaning as ‘flat.’ However, in the scientific context, the two words have different meanings. Insisting that both words to have the same meaning is the fallacy of appeal to definition.

In September 2015, Buzz Aldrin gave an interview at the National Book Festival in Washington, D.C. Flat-Earthers misrepresented and quoted it out of context as if Buzz was admitting that the Apollo Moon landings never happened.
The original interview was 17 minutes long, and there were other occasions Buzz clearly said the Moon landings happened, without any possibility of misinterpretation.

The fallacy of ‘appeal to definition’ is using the definition of a term to support an argument as if the term cannot have other meanings or even conflicting meanings. Flat-Earthers often use this fallacy, for example, over the word “theory.”
A communication problem can occur when a term gets misinterpreted to mean other than what was intended. A simple clarification should quickly correct the problem. The appeal to definition arises if the clarification is refused, and the person insists on using the wrong & unintended meaning of the term, and use it to support their arguments.

News satire is a type of parody presented in a format typical of mainstream journalism. Some satirical news outlets use satirical commentary to comment on actual, real-world news; while others offer wholly fictionalized news stories.
Satirical news outlets have produced some “reports” mocking the flat Earth belief. Unfortunately, some flat-Earthers failed to realize the satirical nature of the “news,” and that the “news” was created to mock them. Because they think it was real news, the “news” spreads in flat-Earth communities as hoaxes.

In an interview, Donald Pettit —a NASA astronaut— mentioned that he’d go the moon, but they no longer have the technology to do that. All the technology from the Apollo mission has been destroyed, and it is a painful process to build it back again.
Flat-Earthers interpreted the statement rather too freely and took that as “proof” we never had the technology in the first place. In reality, the word “technology” is polyseme. It has two different related meanings. Flat-Earthers misinterpreted Don’s statement as one meaning, while Don’s intention was another.

China’s Chang’e 4 spacecraft has successfully landed on the Moon. It is the first ever spacecraft to land on the far side of the Moon.
Unfortunately, some news outlets used the term “dark side of the Moon” which is inaccurate. The side of the Moon where Chang’e 4 landed is not always dark, but instead always facing away from the Earth. That part of the Moon has the same day and night cycle like the side that is facing us and is not always dark.
Flat-Earthers were confused that the spacecraft use solar panels. If the side of the Moon is always dark, then it should be pointless to use solar panels. They took these facts as “proof” of some sort of misconduct. They were simply confused about the term some news outlets were using. The correct term is “far side of the Moon.”

A higher position is farther up, away from the center of the Earth, relative to sea level. Conversely, a lower position is closer toward Earth’s center, relative to sea level. Two positions are level if they are at the same height from sea level.
Some flat-Earthers are unable to understand this. To them, ‘level’ means straight. They are wrong. In Earth sciences, height is measured from a plane of reference, usually the sea level.

The Sun emits sunrays to every direction. But as the Sun is very far, the sun rays that reach us are practically parallel. To an observer on Earth, the rays of light coming from the Sun form a maximum angle of about 0.53°. They are practically parallel, but not perfectly parallel.
Flat-Earthers often question the fact we say sun rays are parallel, but in any diagram of an eclipse, they are drawn at an angle. They merely confuse practicality with perfection. Sunrays are practically parallel, but they are not perfectly parallel.

The directions of up and down are determined from the direction of the Earth’s gravitational acceleration. Up is in the opposite direction, and down is in the same direction as the Earth’s gravitational acceleration.
Flat-Earthers are often seen making fun of this fact. They show us ‘upside down’ pictures taken in the southern hemisphere. They are wrong. To anyone in the southern hemisphere, down is in the same direction as the Earth ‘s gravitational acceleration, the same as anyone in the northern hemisphere.
