I have to disagree in an absolute sense, as it could be right. But that is a question that I don't think science can answer since it deals with belief and faith.
Belief and science don't belong together. There is only level of acceptance as to the validity of the science after having looked at the evidence in a detached, deductive manner. You corrupt the science when you bring belief, faith, emotion, agenda or other outside influences -- just look at the man-made global warming hysteria.
Since evolutionists claim they have no start point, would you agree that the first organic form it could address was probably single-celled?
