Personally, I always argue that if God created the world recently, he specifically designed it to look old; he included light from distant stars, fossils implying evolution, and even created radioactive elements pre-aged. Thus, while technically the Earth may be young, evolution etc. predict what God did with remarkable accuracy, and thus we should use them to make predictions. Furthermore, if God is so determined to deceive us, shouldn’t we do as he wants? :P
