Was Muhammad a real historical figure? What is the evidence for his existence? What is the most verifiable, indisputable, archaeological evidence for his existence?

You can use common sense, or you can believe that there is some vast, ongoing Arab conspiracy that has held up for 14 centuries to invent the Prophet of Islam and make people believe all of this time that he was real.

He was a real person. You don’t have to follow his religion, but it’s silly to say he never existed.
