For clarification, Catholics are not required to believe in the 6 day creation.

For further clarification, Keith rarely gets facts about Catholicism right.
For instance. Papal infallibility.
There have only been 2 Ex Cathedra statements of any Popes. Something has to be pretty spectacular to rise to the level of infallible teaching and it has only happened twice. The Pope isn't infallible by nature of being Pope but he can make infallible statements of doctrine.
For the record, I spent 14 years in the catholic education system but I no longer practice and disagree with the church on a wide range of issues. But if you want to trash something you should have correct facts. Otherwise you look like an idiot.
