Extraordinary claims require Extraordinary evidence not "this book told me."
I would require a multiple peer reviews, physical proof that can be replicated not just personal anecdotes.
Reason requires sound logic not "you don't know everything"
Imagine you are in court in front of a panel of judges and each one has to be satisfied before making a verdict. The judges are logic, forensic evidence, other religions, common sense, science, historian, a linguist and lastly my own senses.
This world is full of cheap stories and intricate lies. One must guard against such deceptions and put them under a microscope.
you would require a peer review study to have a justification of reason itself?
peer review presupposes reason, making the entire process of peer review require reason already.
you ask for "physical proof" of reason... can you find reason under a microscope?
how about "truth" whats your epistemic justification for truth, can we find truth under a microscope?
such as "1 + 1 = 2" - the truth of this statement can we find it in a particular set of matter under a microscope or is the ontological status of truth universal and immaterial
