That’s funny. Catholics say the exact same thing about the veracity of Genesis.
The Church actually gives wide latitude in the interpretation of Scripture. This is especially true with Genesis, which defies simple exegesis. The Bible ("Books") is a collection of books, reflecting various forms of literature, idiom, and style. Daniel and Revelation are examples of apocalyptic literature, for example.
While the content of the Bible is inspired by God, we must take into account these various forms of literature and expression when engaging in exegesis.
