Evolutionists vs Creationists
The first thing to remember is that Evolution and Common Descent are not the same thing. Any semi-educated person should have no trouble grasping the evolutionary notions that "natural selection" and "survival of the fittest" can, over time, lead to changes in the forms of beings. There is no reason for people believing in a creator to deny such occurrences. That all beings evolved from one common ancestor is another matter. Although many people believe it to be so, Common Descent is by no means proven. Nor, is the corollary belief that the common ancestor was not created, but arose from spontaneous generation (abiogenesis). However, there is a reason so many believe in its validity in the absence of proof. It is that, if there is no higher creative power, then, they'll never have to answer for their life's deeds or decisions. Similarly, God(s)-believers take comfort in the belief that a higher power cares about them.
The second thing to remember is that man's failure to "prove" either Common Descent or Creation does not mean that neither is true, or, for that matter, many other alternative origin-of-the-universe explanations are not true. For, example, the possibility that every religion may have the creation story wrong, does not prove there is no Creator.
The third thing to remember is that Creationists don't know whether their creator is benevolent, malevolent, or neutral. A "leap in the dark" is a leap in the dark.
The truth is nobody really knows these things for sure. There is very little reason to support the vehemence of either side in the arguments.
