The main problem here is that creationism (as well as many other theories about the universe and life in general) is mainly talked about within its group. When you go to church, you're told about how God created the universe, the earth, all the creatures, etc, etc. You're not opened up to alternative theories and you don't have a legitimate chance to voice your criticisms and take part in logical debate about the subject.

In my opinion, creationism is completely and utterly without merit. There is absolutely no evidence to support it (contrary to the enormous amounts of evidence for the big bang theory, evolution, etc), and when creationism is bought up in debate, I haven't seen a single clear and concise argument for it.

The fact of the matter is that creationism (and religion in general) should be debated as often as possible. The arguments for it just don't stand up in debate at all, and I think any reasonable person knows this. In my opinion there are two types of people who believe in creationism; those who simply don't understand the alternative, and those who know full well that it doesn't make sense but choose to believe it anyway simply because it is a part of their religion and that is that (please note here that I am not speculating on their motives, be they good or bad). Debating creationism at least allows us to focus in on the first group, give them the oppotunity to understand the alternatives (backed by evidence) and then make an educated decision about their beliefs. In regards to the second group, the most I think we can hope for is for them to at least admit that, while they might believe in creationism, it doesn't really make all that much sense.

The more exposure creationism gets the better. When people know the facts about the baseless claims made by its adherents they'll discard it as nonsense.

Ignoring Creationism will not make it go away.

People need to be convinced that it's incorrect and this requires debate.

The debate should be filed under comedy or religion.
