For me Snail, it is infinitely more important to curb these peoples' attempts to inculcate their dangerous and erroneous rubbish into the minds of our children, disguised as science.

Surely the best way to do that is to present the case FOR science rather than the case AGAINST creationism. You are letting them choose the battleground and define the rules of combat. They have won their first battle by establishing that there is something about creationism that is worth debating. You have given them credibility.
