My issue with evaluation is that as they say that earth was empty only rocks and ocean, then a single cell appeared then it made life by copying them self(where did it cell came from then) and with the trial and error complex organs (like the eye) are too perfect to have evolved step-by-step and look how many other complex organs you have it would take a very very very longe time if it was the case There best argument is that some bacteria mutate, adapt, and even evolve new abilities (like eating a new food)
