Just because something is unanswerable does not mean that your can't make good predictions. I am not 100% sure that there isn't a tiger under my bed. But I am sure enough. I can be 99.9% sure that God doesn't exist and that is enough. And even if the 0.01% is true I have no reason to believe that religious doctrine would have useful expertise on the nature of God. Religion was a good explanation for people living 2000 years ago. People didn't just have "faith" they knew that God had a profound impact on their day to day lives. Slowly but surely science has provided better explanations for all the big questions. Until all religion has left are things that cant be proven to be false. Science won.
