Ken Ham on the Upcoming Debate

Answers in Genesis has written up a pre-debate post on their website.  "Layman" writes:

The agreed-upon topic for the 7 PM debate is “Is creation a viable model of origins in today’s modern scientific era?”
Ken Ham Debates Bill Nye

“A debate with Mr. Nye, nationally known for his children’s TV program and for promoting evolution, will be one of our major events in 2014 to highlight how children and teens are being influenced by evolutionary thinking," declared Ham. “This year, our AiG theme is ‘Standing Our Ground, Rescuing Our Kids.’ Having the opportunity to hold a cordial but spirited debate with such a well-known personality who is admired by so many young people will help bring the creation/evolution issue to the attention of many more people, including youngsters.”

Ham added, “I hope to show Mr. Nye and our debate audience that observational science confirms the scientific accuracy of the Genesis account of origins, not evolution.”

I will be curious to see what "observational" science he brings out. One of the principle problems with the arguments against an old earth is that they cannot be used to show that the earth is six thousand years old. When you read the creationist literature, each of the methods is used only to show that the earth cannot be 4.5 billion years old. There is usually no lower limit mentioned. To my knowledge, there is no observational data that can be used to show that the earth is between six and ten thousand years old or that the earth was under water between 2400 and 2500 B.C.  If Nye takes this attack,  it will not go well for Ham.
