As Will Rogers observed: "It's not what he doesn't know that bothers me, it's the things he does know that just ain't so!"

About any religious person who is 100% sure I recommend the motto:

"Frequently wrong, but never in doubt"

because we are not being presented with any reasonably logical argument, merely the certainty of the believer.

It is the hallmark of religion that precepts be devoutly believed in regardless of all argument to the contrary. This is what distinguishes science and the scientific approach from religion.


An example of this is the 'Rare Earth' concept used to make an argument that creationism is somehow scientific because look at the vast amount of things that have to happen just so our world exists. Unfortunately it is a debating device which sidesteps the fact that whatever the odds may really be, and they are not odds, they are guesses, we already know the world exists, so these requirements have been met.

The Rare Earth theory is dismissed by The Anthropic Principle.
