Is Earth old enough for DNA to evolve?

I have been debating a friend on evolution and he referred me to this video and it has been eating at me... can someone please refute this video?https://www.youtube.com/watch?v=n-BFEhkIujA {The video concerns Mike Huckabee's position on creation/evolution. We need to find a better place for this. Perhaps someone could bump an appropriate topic. - Adminnemooseus}Edited by Adminnemooseus, : Off-topic banner etc.
