Ludwig's WRAP-UP

The phrase "are not exist" is grammatically incorrect and should be avoided in formal writing. The correct forms are "do not exist" or "does not exist", depending on the subject.

Though examples can be found across various sources, including news, science, and academia, their presence does not validate the phrase's correctness. It's best to use grammatically sound alternatives like "is nonexistent" for improved clarity and professionalism.
