Beginning at 6 p.m. CST, Nye and Ham will discuss evolution, the Biblical account of humanity’s origin and the origin of our universe among other subjects. The debate will be streamed online for free from the sold-out 900-seat Legacy Hall lecture arena at the Creation Museum in Petersburg, Kentucky.

According to streaming site debatlive.org, the debate format is as follows:

Each man delivers what he believes is the best information currently available for his case. Each then has an opportunity for rebuttal and afterward answers questions submitted by the audience.

Tonight’s event comes after a spat between the two men that led each to challenge the other to a debate.

Ken Ham, originally from Australia, is the president of the young-Earth creationist organization Answers in Genesis, which opened the Creation Museum in 2007. The museum features displays based on a literal interpretation of the Genesis creation narrative found in the Bible. The museum attracts thousands of visitors each year and plans to spend $60 million to open a Noah's Ark theme park in the near future. Ham holds a Bachelor of Applied Science Degree with an emphasis on Environmental Biology from Queensland Institute of Technology and a diploma in Education from the University of Queensland.

Bill Nye is a popular science educator who once hosted a children’s TV show, Bill Nye The Science Guy. He has appeared on many talk and news programs as a science presenter, has worked with NASA as part of it's Mars Rover program and is a fellow of The Committee for Skeptical Inquiry, as well as the executive director of the Planetary Society.

Both men recently posted editorials to CNN.com explaining why he was debating the other. You can read Ham's thoughts here and Nye's here.
