Asking an LLM is same as asking a large group of people. If the group believes that Earth is flat and Sun rotates around Earth, LLM would confirm the same, if it was trained only on the knowledge gathered by the group. LLM is not a precision measuring tape or a telescope to have its own facts or own reasoning. It's a collective knowledge codified into a single entity.

Can it exceed the collective wisdom of the people? Probably not.
