What an incredibly stupid thing to say. Yes, we do know how the natural world works but it is tenet of Abrahamic religions (and Christianity in particular) that naturalism is not true. And I would not really care about it if these people left it at that. But these people get to vote too you know. What person believes influences strongly what they do and what they want. There is no such thing as a private belief. What you believe about the physical world and what you base your beliefs on determines how you behave, what policies you support, if you will deny scientific facts, what you want your kids taught in schools, etc. If that weren't enough some of these people find it irresistible temptation to "share" their delusions to the point they want their brand of belief instituted in laws and constitution of the country, and things like commandments displayed in schools and courtrooms almost like graven images. This is why they must be engaged in debate, discussion and idiocy of their beliefs pointed out. There is no polite way to tell someone that what they hold as most precious and dearest thing is false, and debunked. But it has to be done, esp. now that we live in times when we do know, are free to say so. And the only reason we are having this discussion is precisely because these people feel the need to discuss and share their beliefs, because they can't be happy until you believe it too, and until every knee bows. The stipulation to proselytize is in the holy books.
