Yes, creationism does fit in evolutionism. The problem with that is that you are adapting religion believes to make sense with the facts of the modern science.
Sure, the theory of evolution I just a theory. However, there's so much material evidence of it that if you separate what we have in a thousand rooms, you would be able to reasonably demonstrate it a thousand times.
Science has to live with the possibility of it being wrong because in science's very fundaments lies the idea that you can never accept anything as absolute, and that every idea can be confronted and proved wrong. However, in the case of evolution, it's so strongly demonstrated that the odds of it being wrong is simply hypothetical. Man, How can someone go to a museum, see the skull of a saber-toothed, or of an Australopithecus and don't believe that species evolve?
Anyway, evolutions basic ideas are rather simple, logical and practical. They dont take much to be understood, but are virtually impossible to stand against. I should know, I simply love to discuss that matter (Im a seeker of controversy, as you can read above my avatar). I already discussed it with dozens of people, and no one ever EVER produced a single reasonable argument, except for the fact that its not proven out of the scope of reasonable doubt.
Its true. In fact, itll probably never be, as most science theories. But let me ask you this
is creationism proved beyond reasonable doubt? No! And, if you have two unproved theories, one backed up by tons of material and evidence, the other by nothing, you should at least lean to the backed up one. Come on, people, for the sake of minimal coherence.
Anyway, creationism guys, just one more thing
There are thousands of religions and thousands of different Gods that could have created the world by thousands of different ways. Why is just the christian monotheism theory being considered here? What about the others?
There is always this people that says that there must be a God because the universe couldnt have come from nowhere. So, the universe cant, but God can, right? It leads us to the plain fact that either we dont know where the universe cam from, or where did God came from.
Mystery for mystery, I say that I dont know about the universe. I need no intermediary to the acceptance that Im ignorant.
