Nye: limestone layers in Kentucky contains mature coral - millions of layers. Also thousands of layers in ice cannot be formed in the creationist timeline.
Nye: animals were able to get to Australia over a land bridge, but there is no evidence of a land bridge. According to the creationist model, there would need to be some fossils (such as kangaroos) in Asia.
Nye: the number of species (16 million) came from 7000 kinds, according to Ham's view of 4000 years timeline. This would mean 11 new species every day.
Nye: it is unlikely that Noah and his family were able to build an ark of 500+ ft. He cites a modern example of a constructed wooden ship (smaller than ark) that sunk.
Nye: example of the Canadian "fossil marsh" where fish-lizard "Tiktaalik" was found following prediction of scientists holding to evolutionary model. Nye claims that Ken Ham's model would be unable to do such prediction.
Nye: Hubble observed the stars moving apart; Hoyle supposed this was because of a "Big Bang" (hence the model of the same name). Big bang "echo" detected in subsequent years, supporting the previous astronomers' predictions.
Ham acknowledges that we can "observe" radioactive decay. Ham cites example of wood and basalt in same layer measured to be vastly different ages. Another similar example provided to show that dating is unreliable and based on assumptions pertaining to the decay rate.
Ham acknowledges that some Christians believe in millions of years of history, but they are being inconsistent because this requires belief in millions of years of death and bloodshed. He claims that the only infallible dating method is the "One who was there" (i.e., God).
Nye: astronomers observe the past, this occurs when light is observed. Re-asserts that there should not be a separation between present and past observations and natural laws. Identifies point of contention is uniformity.
