1. First segment, where YECs get to propound their principles of cosmology, universal age, and the size of the universe without resorting to any scripture, and without making any any attempt to specifically discredit evolution (and if they are offering up principles which require changing constants such as a shifting speed of light, clearly stating the scientific principles which buttress that belief, the amount of change, and the names and credentials of the scientists who postulate it).
2. Second segment, where YECs detail their criticisms of evolutionary theory, without resorting to scripture.
3. Third, YECS will get to defend their beliefs in an inerrant and short timeline of scripture by offering up their absolute proof of the events referenced in the books of Genesis and Exodus.
Yes, since the 'scientists' of evolution cannot support their theory with scientific facts, then let's turn the thread over to Christianity bashing, at which they are really good at (but of course they will not admit that they are atheists).
