Bill Nye debates Ken Ham on creation vs. evolution

Watch Scientist Bill Nye debate Creation Museum president Ken Ham in Petersburg, Ky.

TV's "Science Guy" Bill Nye defended the vast evidence behind evolution Tuesday night while sparring against the founder and CEO of Kentucky's Creation Museum, Ken Ham.

The debate, streamed online from Ham's home turf, lasted for more than two hours and included full open statements, 30-minute presentations from each side, and a Q&A section over evolution vs. creation. Thousands of online viewers tuned into livestreams of the event; at one point, the debate surged as a trending topic on Twitter.

"I take this business very seriously," Nye told MSNBC's Lawrence O'Donnell following the debate. "If we raise a generation of students who does not know and appreciate the process of science--let alone the facts of science--then we're in trouble."
