Literal Versus Allegory and Metaphor

Liberal religious beliefs came up again today, this time with the assertion that religious texts like the Bible aren't meant to be read literally. Mostly. Sometimes. Whenever we have verifiable evidence that whatever is being discussed has been debunked. Furthermore, someone claimed to me that most religious believers don't take their scriptures literally.

Naturally, this required some verification.

Nearly 8 in 10 Americans believe in angels. Literally. Why? It's largely driven by religion.

64% of Americans believe Jesus literally died and was resurrected. Not metaphorically but literally.

46% of Americans believe that humans were created, not evolved, in their present form within the last ten thousand years. Nothing metaphorical about it.

80% of Americans believe in miracles. Not allegory, not metaphorical miracles. Miracles on par with what's recorded in the Bible.

Tell me again why I should assume religious beliefs and texts aren't being taken literally?
