Last week, creationist minister Ken Ham responded to a NASA astronomer's estimate that "in the next 20 years we will find out we are not alone in the universe" by declaring the search for extraterrestrials "pointless" because they're all going to hell anyway. Neil DeGrasse Tyson, astronomical badass, went on Real Time With Bill Maher Friday to offer a well-reasoned counterpoint.

Ken Ham, the young-Earth creationist minister who had his ass gently-but-firmly handed to him in a debate with Bill Nye earlier this year, has had it with "the desperate and fruitless search for extraterrestrial life." Aliens can't be real, because the Bible says Earth is special. And if they are real, they're all going to hell.

Last night, Bill "The Science Guy" Nye debated Ken Ham, a noted creationist, over the question: "How did we get here?" The debate, which took place at Ham's Creation Museum in Kentucky, lasted nearly two and a half hours and went about exactly as you'd expect.
