I saw about 40 minutes of it, entertaining.
Ham (Creationist rep) was a young Earther and mainly just lectured on Bible verses while Nye (Science Guy rep) seemed very prepared for this show (which is all it was) and he lectured the Creationists on rather basic facts like the speed of light and how far Australia is from Mount Ararat, and that the creationists have not come up with a single Kangaroo bone between the two places many thousands of miles separated.(none of that is new BTW)
That forced Ham (Creationist rep) to argue that there is not a single law of science observed today that we can assume applied even a few hundred years ago.
That's a desperate stretch.
6,000 years vs. 4.5 billion years isn't really within the margin of error. Someone is very, very, very wrong.
That is what the Islamic fundamentalists argued to shut down scientific progress in the Arab-Islamic world back in the Medieval period. They claimed those who thought nature is governed by natural law limited Allah's freedom of action. Trying to find natural laws was a waste because Allah at any moment can change them and further such laws were blasphemous. Shows how Ham and his ilk go against millenia of Christian philosophy and theology that has supported scientific research.
