As a literalist, or letterist, nothing about the Book of Genesis indicates that it's to be interpreted as allegory, poem, parable, etc. My slippery slope comment wasn't a dig at SA more than it was a statement that I have to walk the walk. I believe that the Bible should be interpreted literally unless it's obvious it's not supposed to and there's nowhere in Genesis (or in Job, etc) that indicates that.What made you switch?
There were quite a few things that made me switch. The hebrew phraseology makes it clear that we were a special creation, imagers of God, not so much in how we are made (like out of a "mold" of God), but our function on this world.
The layman's term for the Genesis 1 people would be an idol, or literal manifestation of God in our world. These ideas do not jive with theistic evolution, or that God created the amoeba that turned into us (I'm speaking generally).
