It's just so much easier to conceptualize that everything came from the Big Kaboom without worrying about the ingredients (since science clearly tells us that everything can come from nothing)  and that dumb "luck" just happened to put the DNA sequence together (despite the odds of that happening were, let's just say, "remote").  We scientists who happen to be Christians (talk about an oxymoron) just need to learn to keep things simple...like keeping faith.
