Definition of Evolution
Biological evolution is defined as the descent of living things from ancestors from which they differ. Evolution kicks in after there is something, like a replicating structure, to evolve. So the origin of life preceded evolution and is conceptually distinct from it.~ Dr. Eugenie C. Scott (born:1945-10-24 age:70) Evolution vs. Creationism: An Introduction, Second Edition
Creationists make no distinction and like to falsely claim that because science has not definitively cracked the origin of life problem, there must be something deficient in the theory of evolution.
