What evidence absolutely rules out a Creator

If fossils say what we think they say, then evolution is true. Logical leap that lands you in hot water. You've just argued that the existence of animals disproves God. All animals feed off other life forms in order to survive. Herbivores eat plants, carnivores eat other animals. Who cares about the fossils - currently living animals are enough. So you made up a God, and disproved his existence. Now, JHWH, that jealous God who is Wrath, the one that asks for animal sacrifices - is he the kind of God who'd have a problem with a biological killing field? This is the kind oF God that allowed Job's life to get seriously screwed up, just to see if Job would curse his name.That kind of God is perfectly capable of making life on earth a killing field - just to see if we keep faith. Except that they only disprove your specific definition of God...not everyone's definition of God. You don't get to decide which definition of God is the right one I'm afraid.

Theologically speaking then, before the Fall, all creatures, including humans did not know the difference between right and wrong. Adam/Eve did not kill any other creatures - they were the first to have an awareness of what not to do (disobey God) yet they did it anyway.Evolution does not rule out a Fall at all. Everything up to the Fall could have evolved as we know it with no sin (you said it yourself, there is no sin without a concept of right/wrong). Humanity was given the concept of right/wrong (don't disobey God). They disobeyed God, and fell into sin.It's probably the clearest argument you've put forward, but it fails to formal logic because it excludes other possibilities. The nature of reality raises some questions theologically. Why was there a pre-fall killing field? Unfortunately, since we don't know the reasons why God decided to create the universe/life/humans in the way he did, we can't assess using our good/evil knowledge whether or not those reasons were good or evil.
