Sure, scientists working on evolution theory have stuff they can't explain. There's some wierd shit out there, mainly cos genetic mutations are random and hence unpredictable - also, being random, there's the possibility of the same mutation occurring spontaneously in 2 different places, which'd screw up your time-line good style.

The thing is, no scientist ever says they know everything about a field. Science is about investigating, checking that what you think is happening is actually happening, etc. Think Newton vs. Einstein - Newton's theory was fine for most stuff, but it broke down at high speeds. Einstein produced a better version which explained the time-lapse as you speed up, but there's still stuff in there which isn't answered yet, even 80 years later after the attention of dozens of super-genius physicists. Someday, someone will solve it, and then there'll most likely be another puzzle inside that to solve.

It's like the old saying - inside every small problem is a large problem waiting to get out. The deeper you dig, the more complex you find the universe is. But the key is that scientists are prepared to dig, find out stuff, think up new theories to explain them, and ditch old theories if they don't give a good enough explanation (or if they're proven to be just plain wrong).

The moment anyone says, "Well, it's obvious, it's God, there's nothing we can do about it, and we shouldn't meddle with His handiwork", they may as well go back to their cave and chant to the Big Light In The Sky. Belief in God is fine - I personally believe in God (although not in Christianity) - but the moment someone insists that theoretical reasoning and dogma MUST take precedence over provable evidence, they've stopped being a reasoning being. They've proved that they're not capable of thinking for themselves - and why should we take notice of someone incapable of rational thought?

Think back to the Greeks, the masters of intellectual argument. Lacking the ability to carry out complex experiments, their theories into physical phenomena threw up some bizarre theories and paradoxes - the proof that the tortoise can always avoid the arrow is just one (Xeno's paradox?). Or even in our times, think of Freud's conclusions which sum up roughly as "women don't find pleasure in sex, therefore there must be something wrong with the women". If pure theory doesn't match with the real world, the problem is with the theory, not with the world! :-)

The moment you introduce the possibility of an infinitely powerful God into calculations, working anything out becomes impossible. As soon as you find something you can't immediately explain, it's obvious that it's God at work, not some physical phenomena which you've not thought about but could conceivably solve with some serious thought. The Deus Ex Machina may have a simplicity to it, but simplistic solutions are only suitable for children - the real world is complex, and hiding from it is not a solution.
