What is "rational" about believing in a phantastic claim?
You are either not very educated person, or you are maybe still in your teenage years, since you don't understand the meaning of the word axiom. I wish you find a way to learn about logical definitions and conclusion procedures, it will help you in your life.

"An axiom, or postulate, is a premise or starting point of reasoning"
