I personally think it is called mythical.
No, it isn't.
Green cheese.
This is a classical example of a tautology. The sentence "if [P and Not(P)], then Q" is always true, regardless of the truth values of P and Q. This is the principle that, from a contradiction, anything (and everything) follows as a logical conclusion. Essentially, assuming something that can never be true is true ("If the moon is made of green cheese"), you can prove anything. Thus the statement "If the moon is made of green cheese then pigs can fly" is true.
In year 1546 John Heywood suggested the Moon is made of "green cheese." But not the color green- by "green' he meant fresh and unmatured.
Nooo the moon is NOT blue cheese- IT is a specific material made of matter with crates in it...
I know that it is not made of green cheese.
You make a statement that is either a true one or a false one. Simple as that. For example, you might say "The moon is made of green cheese" as a false statement and most people know that's wrong.
The phrase comes from a fable or proverb in which a simpleton looked at the reflection of the moon in water & thought it looked like a wheel of cheese. The 'Green' comes from young cheese. Naturally there was never a historical account of people believing it was made from literal green cheese.
Any fanciful notion has always been compared to the nonsense idea that the moon is made of green cheese. In other words, if you can believe that, you will believe anything.'Green' does not refer to the color, but means the cheese is 'young', not properly aged yet.The actual kind of cheese is not specified.
"Tom thought it was a fallacy that the Moon was made of green cheese."
the moon isn't made of cheese....
Green cheese. That is the mythical saying. The moon is actually made of one big rock floating in the earths orbit.
It is not made of Cheese!
