Or, you know. All science that we see everywhere is true because God did it. Why is it so hard for these two views to coexist? God made the universe able to run on science. He made it with a firmly established set of rules for physics, biology, geology, etc, etc... Why is this so hard to understand?
This is the closest I can come to believing in "divine creation of life" in any respect.
Science has presented plausible theories for the existence of the universe all they way back/out to the Big Bang. If you ask a proper astrophysicist what existed before the Big Bang, she will say "I don't know." So if I wanted to believe a god had any hand in creating our universe (note: the whole universe, not just Earth - we aren't special), the only thing that makes sense in the face of all our scientific observation is that a god started the Big Bang, laid out the laws of physics, and sat back to watch the longest game of Pachinko ever.
Everything that's happened since then can (or will eventually) be explained without any need for divine influence.

Regarding the rattle-less snakes, there is no effective difference between natural selection and dog breeding on a functional level. In either case, the animals that breed/survive are those with specific traits. In the case of dogs, humans are selecting traits they prefer (and it's worth noting that for all our tinkering, a "dog" is still more or less just a funny-looking wolf). In the case of the rattlesnakes, snakes with less rattly rattles are surviving to reproduce. Note that these aren't speciation events -- they are examples of changes over time in the frequency of certain genes in a single species. Another classic example of this is the Peppered Moth in England during the Industrial Revolution. It hid on pale trees, which became stained black from soot. In a span of 50 years, peppered moths went from nearly all (99%+) white to nearly all (98%) black, all because a mutation suddenly became better camouflage than the "original" coloration.
Naturally, there's the question of how a "rattlesnake" becomes "something other than a rattlesnake" -- how one species evolves into another. Evolutionary scientists have observed this in the modern world. A species is defined as a population that can viably interbreed, so it follows that speciation occurs when two groups of the "same species" change enough relative to each other that they can no longer interbreed. Unfortunately I can't find a reference for this, but the first example I read of this was a mouse in (I believe) the western United States. Three distinct populations, separated by mountain ranges, were observed. The central population was able to interbreed with both the western and eastern populations. HOWEVER, the western and eastern populations could NOT interbreed. They had diverged too far. I believe the three populations are categorized as subspecies.
And of course, on the very-long-time-frame scale there really isn't any such thing as a species "changing into another species." Whales used to live on land, but over thousands of years spent more and more time in the water. Whales born with smaller limbs and more streamlined bodies did better at it - a selection which repeated generation upon generation until whales were being born with truly tiny, useless limbs, and then entirely internalized leg bones. You could never look at a single birth event and say "yep, it's a whale now." Meanwhile, some pre-whales didn't go in the water. Over time they ended up looking like horses, hippos, and pigs.
Here are several more examples of observed speciation, including lab-induced speciation in fruit flies and observed wild speciation in fish, plants, and birds: http://www.darwinwasright.org/observations_speciation.html (sources at the bottom of the article)
