In the same way, Christians believe in salvation through Christ's works, and the details in the natural history, and human behavior requirements are minor details.
I'll not argue with your assertion about human behavior pertaining to adherence to biblical laws being a "minor detail." However, the "details" in natural history are, at least to the worldview of a fundamental Christian, anything but minor.
Take, for instance, the Garden myth: allegedly, a few thousand years ago, the sun, moon, stars, heavens, earth, plants, animals and humans were created. Animals lived side by side, eating nothing but plants (tigers eating bamboo!), and there was no death until *oops!* Eve and Adam boofed the pooch. Thus, The Fall
®.
Never mind that there is
ample (some would say
overwhelming) evidence that the Garden myth is just that: a myth. The fossil record indicates copious death millions upon millions of years before humans ever hit the stage, so to speak. To a literalist, this is anathema since death before The Fall
® renders Christ's death and resurrection pointless, no? And this isn't even getting into the fundy's suggestion that if even one part of the bible is suspect, then that renders the
whole thing suspect. Thus the recalcitrant, irrational, unreasonable literalist arguments against anything which smacks of *gasp!*
evidence, even if such evidence is undeniable and plain. And this is just one example.
So your statement that natural history is nothing but "minor details" to a Christian seems, to me, to go over like a lead balloon. However, the fact that a biblical literalist
would indeed consign all geological, cosmological, archeological, genetic, etc evidence to the trash heap of "minor details" would certainly not come as a surprise to many.
Have a good one.
