The church I used to help lead put on a "Cafe Theology" for the church where we took some time to dig into big topics. I presented four main views of creation along with a summary of how to read the bible when engaging with these big questions. We then had a panel answering questions - due to the break in relationship with the church I've removed the panel but kept my presentation.
I hope you find it helpful and as always, am very interested in your feedback or questions!
