Burden of Proof

[Mark 13:13]

Well the obvious thing to do is ask him to take you to his back yard so you could see for yourself but im afraid in our case I can't have you walk in my backyard as my backyard is my life so we are at an impass. But it doesnt mean we cant discuss and it doesn't mean there isn't a flock of dragons in my backyard..

The dragons are invisible, remember? A trip to his back yard would not disprove their existence.

The guy claiming there are invisible dragons, could constantly come up with the exact same kind of rationalizations that you can't detect the invisible dragons as you use.

"Oh, you can't rely on evidence or reasoned argument to detect the invisible dragons, you need to use the tools appropriate for detecting invisible dragons".

Problem solved, right?

well answer still stands except of course as well as the dragons I might find the tools for detecting them that the guy had as well.
