Fire up the church van: The state of Kentucky is offering big tax incentives to investors who help build a full-size replica of Noah’s Ark. It’s being built as an attraction at a theme park by the same people who run Kentucky’s Creation Museum. They’re hoping the two attractions, in tandem, will create a Christian tourism corridor in the state. The ark will be built from wood by Amish builders, and the park will also include a Tower of Babel. Constitutional experts are asking whether the state’s tax offer violates the constitutional separation of church and state.
