Note that for evolution to happen you need two things.
1. You need to have heritable features and either genetic mixing or errors in copying.
2. You need some sort of "pressure" ie, not every living thing will procreate equally, but those with certain feature will procreate more.
If you have both of these things, and we do, then you will get evolution. It's an unavoidable certain effect of the above two situations. Denying evolution is therefor on the level of denying that 1+1 = 2.
This does not prevent there being a creator, or somebody guiding the evolution. Realizing this is Darwins great achievement. (He didn't discover that animal evolved, scientists already knew that, the question was how and why).
Evolution doesn't even contradict creationism. The world could have been created 6000 years ago, or even 10 seconds ago, and evolution would still be a fact. Claiming that evolution is fiction or just a hypothesis is therefore just silly.
