While I do not entirely rule out the possibility, I have not yet been convinced. I have seen numerous lines of evidence, but they mostly rely on base speculation, ignorance and emotional bias. Show me something concrete, and just maybe a believer could be made out of me.

The question is....how can the Bible be taken as absolute truth?

Bonus question: Why did you not even try to provide evidence from outside the Bible?

I think there can be, and are, religions that eschew supernaturalist concepts.

Examples?

I do know that some schools of Zen Buddhism attempt to stay away from the more supernatural aspects inherent in other Buddhist sects, but I would argue that Buddhism can be either a religion or a philosophy or a religion, and loses its religiosity when it casts aside its supernatural elements.

Also, if religion is not necessarily reliant on supernatural components, what would the word used to describe such a supernatural philosophy. Would there be none? Is there no value in differentiating between naturalistic and supernaturalistic philosophies?

In his youtube series "Foundational Falsehoods of Creationism", user AronRa claimed (and I am paraphrasing here) that "all philosophies described as a religion by both their detractors and supporters make claims regarding what happen to people after their physical bodies die." I am not sure if this is strictly true, but it does fit with all religions I know of. How the religion handles this concept varies wildly, but it seems to be one of the only universal components of all religion.

At a different point in the series he offers that all religions require faith. And since no concept of "afterlife" happenings can be fully confirmed or denied objectively, faith would be requisite.

So, I guess that my answer would go something like this:

"A collection of beliefs and practices stemming from particular, faith-based notions disputing the finality of death."
