You would be correct to say that the main thrust of debate centers on theistic evolution and young earth creationism and all the subtopics that come about.
I do not know of anyone on here who is not Christian. In fact, you may have noticed that this is a "Christian Debate Forum (All Christians)" meaning that everyone here has at least convinced the administrator that they are of a Christian denomination. No one seems so far out that I would suspect them of having come here under false pretenses. I think that most here, even those that support evolution, are Baptist.
Notice above that I expanded your intial wording to say "young earth" creationism. That is because since we that are here are all Christian, I suspect that we all would all be some form of Creationist. We just do not all believe in a recent creation or in a literal interpretation of Genesis. A number of us do not believe that the evidence seen in the world and universe God has given us is consistent with a recent creation and therefore that there is a different meaning for us in the creation account than just a retelling of history. Others strongly disagree. And that is the crux of the debate here, how old is the creation and how did the things we see here today get here.
This forum can be a bit tense. There are some that I wish would stick to more facts and less name calling before we all get on the bad side of the administrator and get this forum shut down (again). But in the end, we are all on the same side, even if it does not sound like it. I lurked on this board for a long time before I joined and I have been an infrequent poster. There used to be a time when this forum was full of atheists and it was a very rough time then. It was eventually shut down for a while and then came back in a manner where all posts had to be emailed to the administrator who would review it before adding it. That did not attract much attention. I am grateful that we have the forum back to its current state, even with the occasional un-Christian responses.
If you feel like it, jump on in, the water's fine. Most of us don't bite. Also, I have painted with a very broad brush here so don't think what I say is close to universal, just an opinion.
