How do you handle it if your LO attends a daycare or preschool at a church or temple but you're not religious?

Our daughter recently switched to a church based daycare/preschool because it is much closer to our house than her old school. Neither DH nor I are religious or know much about the bible. She's been coming home talking about some of the stories or singing songs she's learned in school. I don't have a problem with her learning bible stories but I feel kinda stupid for not knowing what she talking about.
