Like the old guy said, there would be very little to teach. Most of our history, culture and traditions come from religions of all types. Unfortunately, most of our wars too. We can really see this today.
As I am reading science today, it seems to me that the scientists are becoming the people who are really searching for God. The discoveries they are making are holding them in awe more that many different religions...and like religions, most of what they find, they have to take on faith.
Properly understood, there is really no conflict between religion and science if one would use their common sense one could see that clearly.
