Because you guys are still unable to comprehend that, for example, you can't watch CNN on your lawn mower. Natural selection ONLY applies to existing, living things, capable of producing offspring. Conversely, when you are talking about origins of life, you DO NOT have the factors of adjustment of the organism to the environment, transforming energy, producing offspring etc. Yet GGG wants to mix these two things, to produce an argument that natural selection doesn't work. Sure, your lawn mower doesn't work either! Can you watch CNN on it? No? Gotcha!
So, what do you want to talk about today? The origins of life? OR how the existing life evolves?
It seems that adherents to evolution have a greater faith in God as the creator than the YECs on FR do.
