I'm presently having a friendly debate with a young-earth creationist. However he is trying to use the argument from the uniformity of nature to claim that my worldview is irrational (since I can't explain why science/logic work and I'm assuming the universe will continue to be predictable in the future without any proof it will be or why). Of course "the god hypothesis" explains all that...lol, but he tries to use it to undermine using science/logic to argue against the existence of a god. It's been an amusing debate at times, but he won't let that point go. I mentioned how he was being like the villain in Ayn Rand's "Fountainhead" who said something like "And if they say it doesn't make sense, then you must be careful to cut the supports out from it. Tell them there is something above sense. You don't have to be very specific...".
