What type of argument restates the main point without presenting any evidence to support it?

The type of argument that restates the main point without presenting any evidence to support it is often referred to as an assertion or a bare assertion. An assertion is a statement that is presented as a fact without any supporting information or reasoning to back it up. In a logical argument or debate, simply making an assertion does not constitute a strong argument, as it lacks the necessary evidence or premises that would convince others of its validity. For an argument to be persuasive and credible, it typically needs to be supported by evidence, examples, statistics, or other forms of justification that can substantiate the claim being made.
