When I discuss religion here, it is usually about claims that theists make based on their respective religions. In most cases, those claims and religions get their details from what are deemed “holy books”. These can be anything from how the universe came to be, to how one should eat, or how one should treat other people, etc.
Many theists want to start with a presupposition, that their holy book is true. What they forget is that to everyone else but a believer, it is a set of claims.
The Department of Communication at University of Pittsburgh has a great explanation of how claims, reasons and evidence works. Claims aren’t evidence of themselves like the theist presupposition requires. They can be evidence that people did indeed believe such things, but they are not evidence that the events happened or the beings existed.
Addendum: if you want to see me discuss this with a Christian, go to Joe’s blog here: https://trueandreasonable.co/2014/12/23/no-evidence/ At this moment, if my posts are still up, Joe is trying to use trial lawyer arguments for evidence for his god.
