Sorry to burst your bubble, but the majority of Christians do believe in evolution.
Duh! Why do you think I keep singling out creationists? Do you think I live in some magic kingdom where everybody is an atheist, tibear?
Christians believe that God created the universe and evolution is simply how he did it.
No, that is what most Christians believe. Those that believe otherwise have been backing a very real push to have their decidedly non-scientific beliefs taught in science class. I'll let them do that the day they let me teach their Sunday School classes...complete with beer, smoke and some props that would make the preacher's skin turn orange.
Creationists are free to believe their theory if they want, it is simply another way that God could have created the universe.
They are free to believe whatever they want. The second they start mumbling that it is valid science, or using to undermine scientific theory, then they become fair game. Given their actions in the US in last few years, it's open f*cking season.
