Literal is a confusing word. I like to take what Gluadys gave to me a while ago: the first meaning of a word in a dictionary is its literal meaning. If so, the meaning of a word given by dictionary will be non-literal in most cases.
So, if people asked me about literal understanding of the Bible, I would simply say yes first, then if chances are given, go ahead to debate about "various" ways of literal interpretation. This will blow the mind of philadiddle away. How could I be literal and non-literal at the same time?
The thing is that even with an interpretation, Darwinism is not implemented. The laws in place governing the nature of life are extensive and Paul briefly outlines it in 1 Corinthians 15:39
All flesh is not the same: Men have one kind of flesh, animals have another, birds another and fish another.
In recognition of the fact that matter is a reflection of, obeys, was birthed by and is subjugated by spirit those laws are applied to life as it appears to physical man. Given that alone, the proposition that man can arise from microbes is preposterous. It is not in the literal interpretation of the bible, it is not in metaphorical interpretation of bible, it isn't in a bible read from atop a fridge, from under a bed, or on a tightrope. In fact, one of the most extensive interpretations you may find on the internet comes from
Bible Meanings Home and even there you find the creation of the "Celestial" man and the "external" man.
Texts deal with origins and depict a past with metaphysical elements. Physical science, which cannot recognize metaphysics, want to theorize about origins. Inevitably they clash.
Additionally, according to the principle of linear progression man advanced from a state of ineptitude to scientific supremacy since his conception. You have God which was evidently as commonplace to the ancients as the air you breathe. But physical science cannot grasp it. By comparison, given the present vacuous state of suspension, the ancient concepts must either be behind physical science in a state of primitiveness or it must be ahead of it outside its scope. According to Darwinism man could never have been more advanced than today, so God must be a primitive concept. From there texts are debased in order to exemplify symptoms of ADI (Ancient Darwinian Ignorance).
