You should realise that the theory of evolution doesn't threaten Christianity. All the major Christian denominations accept evolution.
Evolution is only a problem for those who take the extreme view that the bible is absolutely inerrant and literally true in every word. Those people assume that God never speaks in metaphors, despite Jesus's common use of parables. Importantly, the literalists all believe that every word of Genesis is literally true in every respect - i.e. it describes things as they actually happened. Thus, if Genesis says God created man out of dust, then that's what happened, literally. As far as fundamentalists are concerned, there's no arguing that this is a metaphor for God defining the laws of physics and chemistry, then setting in train the process of biological evolution, determined by those laws.
The view that the bible is literally true in every word is obviously unsustainable. You only need to read the bible to work that out. For example, even in Genesis, there are two conflicting accounts of Creation, which differ in the order of events and other details. Literalists will, of course, go to great lengths of contorted reasoning to explain away the obvious inconsistencies.
At the same time Darwin wins a little more respect from me, and I continue to have my faith the same as before -- it is not at all threatened by the theory of evolution except in one place -- the origin of man.
That's only a problem if you believe in Special Creation of man as a being totally separate from all other life on Earth. All the science, of course, gives us no reason to suspect that man is fundamentally different from all other animals in any biological sense. If I recall correctly, there's no direct statement in the bible which even says that only human beings have souls.
Literalists take an anthropocentric view. They assume they must be special - that they - and only they - were created in the image of God, separate from all other animals. Like so many of their views, this one is easily dismissed by actual scientific evidence.
I feel good about a God that would make nature able to take care of itself and keep itself in check through adaptation, "evolution" as you will.
Personally, I think a God who designed evolution would be infinitely more admirable than one who created each creature as a one-off production. Such micro-management seems particularly wasteful and unlikely to me.
I still feel that some of the gaps are probably too large to span, but that's just a personal opinion.
Which gaps, in particular? Perhaps we can help.
