The problem with Creationism, aside from there being no evidence of any kind to support it, is that if there is a God, Creationism necessitates him being a conniving and purposeful liar. Hiding dinosaur bones all over the planet, along with the humanoid bones of what appear to be our ancestors, in minute detail, just to trick us into thinking he doesn't exist? That's pretty hard to swallow.

What did Sherlock Holmes say? "The most obvious answer is most often the correct one." Something like that. The simplest explanation for there being dinosaur bones all around the planet that carbon date to many millions of years ago in time is that there were dinosaurs many millions of years ago. The simplest explanation for the fossil record showing increasing complexity in lifeforms over time is that lifeforms grow more complex over time.

There's no reason to inject religion into this other than that the material facts don't match this or that piece of religious writing. That's the problem with religion mixing with science: religion tries to make the facts fit the religion. Science doesn't try to make the facts fit anything; scientific theories are refined constantly to reflect the available evidence. Most scientists are willing to accept that God created everything, even a mere 6,000 years ago or whatever, provided that that is what the evidence shows. But it doesn't. Creationists are not nearly that flexible. If the facts don't fit their beliefs then either the facts must be wrong, or God did it all just to trick us.
