Christian Challenge will be holding a free debate in White Concert Hall 7 p.m. Sept. 21.

Frank Turek and Jeffrey Jay Lowder will discuss whether naturalism or theism is a better answer to explain reality, or if there is some grey area between that would better answer how reality came to be.

Turek, doctor of apologetics, is an award-winning author and president of CrossExamined.org.

Jeff Lowder is co-founder and past president of Internet Infidels Inc, a principle website for atheists.

Christian Challenge asks that people bring a can of fruit for the Washburn University food pantry.
