One of the problems with the idea of evolution is that we never see any creatures evolving into a more complex, different kind. Evolution of this sort (macroevolution) has never once been observed.
Variation within kinds which we do observe (microevolution) is not the same as macroevolution, and the former has never been demonstrated to lead to the latter.
Science deals with what you can see, observe, record, test, repeat, etc.
Evolution (macro) can not be demonstrated or supported with the scientific method. The current atomic theory can; the theory of gravity can; but evolution can’t. How many experiments do you know of that demonstrate amoeba-to-man evolution? None.
Evolution (macro) has never been seen, repeated, recorded, etc., so it is neither a scientific theory nor even a scientific idea. It's a conjecture, an unsupported leap of faith, and worse: a lie, since God already said how He made things.
