Bill Nye the Science Guy debated creationist Ken Ham last night (Feb. 4), and it's already been uploaded to the web.

The showdown happened on Ham's home turf, at the Creation Museum which he founded in Petersburg, Ky. Moderated by CNN's Tom Foreman, the debate centered around the question "Is creation a viable model of origins in today's modern scientific era?" and featured questions from the audience.

Nye is a longtime science communicator and the current CEO of the Planetary Society. His opponent is a "young Earth" creationist who reads everything in the Biblical book of Genesis as literal truth. You can read more about the debate here.
