I don't know that your premise is correct. One, it doesn't seem to be the case that you can't start of with an assumption. In fact, unless I am gravely mistaken, along with observation, that actually where you start off, with science or just about anything else.
If you're trying to prove something right or wrong, you first have to have an hypothesis TO be proved right or wrong.
So there's that. It's valid enough, in other words, to start with an opinion, and then see if the opinion is justified in light of evidence.
For your Koran, mentioned in the post before this one, one possible "testing" question, and one which seems reasonable enough to me:
What do nations that follow Islam, that follow the Koran as the basis of their laws, customs, habits, practices, etcetera, what do they look like? How do they function, especially compared to societies that follow the Bible as a major or even the major basis of their functioning?
In other words, if the book the religion is based on says,
"In this day and age, do x,y,and z"
and you do so and get what was predicted and good results ...
I find it telling that the biggest charge people lay against Christians is that they don't practice what they preach.
By contrast, people actively fear some Muslims precisely because they DO practice what they preach. No less a figure than Richard Dawkins is willing to give some ground on this particular point, and earlier in other threads I posted a clip corroborating that.
