First of all, I believe that it is quite possible that the idea that god created the universe and that life evolves can both be true.
I also believe that what the creationists/intelligent design people are saying is that god created things, including life, perfectly and as they are right now. Their position is so untenable it is even hard to define. For example, and on the simplest level, they don't account for change even though change can be seen with the common eye. How can you believe that the design of anything is the only form it has ever been in, if it can be proven empirically that something or some part of a thing has changed.
Intelligent design/creationism, is a false theory, which talks us out of our own eyeballs (senses), to further a political agenda. Namely, if we can destroy science in the name of religion, than we can also destroy bipartisonship and make everyone see things the same way, the Christian Fundamentalist way.
Creationism/ID is not a theory, it's not even a hypothesis.
No, it is a fact. It is undenable, given the overwhelming weight of evidence, that life evolves. We see it every single day. Precisely how it evolves and what mechanisms are involved in that evolution may be questionable, but the fact that evolution occurs is not.
That's like saying that people only believe gravity is a fact.
First off, evolution and creationism are not necessarily mutually exclusive since evolution does not attempt to "explain" how or why life came to be. Merely how it evolved once it DID come to be.
But no, I do not believe in any sort of mythological gods or goddesses blinking "life" into existence.
I had some die hard creationists in my raft once on the New River. They were quite hilarious. Apparently dinosaurs never actually existed. All the fossils were planted by the "devil" to misdirect us. Everything on the planet now is exactly as it was at creation - which according to them was 6000 years ago. (and that's what I've most often been able to determine the bible figuring) And NOTHING existed prior to 6,000 years ago.
So, while we're on this river that has CUT A GORGE through a MOUNTAIN THAT WAS LEVELED BY GLACIERS, I mention volcanoes and oh... I dunno... RIVERS to this group of obviously misguided, but well-meaning souls. They said rivers don't cut through mountains, and volcanoes don't create new land. That the earth - as it is now - is exactly as it was at creation 6000 years ago. Nothing has changed, nothing ever will.
I seriously just sat blinking at their sheer willful ignorance for a few seconds before pointing out a blue heron that landed on an island in the river and trying to divert the conversation to anything BUT their ludicrous notions about creationism. Because I really didn't know how long I'd be able to keep from busting out laughing. I did manage to though, and get a pretty decent tip from them.
I guess they never heard of the Hawaiian Islands which are still being formed. I believe there is also an island in that chain that hasn't reached the surface yet. So much for that idea.
