(V): "Now, that depends on what you call evil. If all life is generated from God, then even the nasty parasites, bugs and diseases all come from him. The story of Moses seems to confirm this point, as God is blamed for the ten plagues."


Nope. You are making the same assumption, that before everything changed evil was already here. The effects of evil aren't limited to us, even though we are responsible for letting it in.

Natural selection is sensitive to changes in environment. It's a blind process. Natural selection didn't sin, we did. But if you open a door and let smoke from a pulp mill in, you won't be the only one (or only thing) affected by it... the smoke will get on and into anything it comes in contact with.

We are not only responsible for what happened to us, we are also responsible for the effect it's had on all of nature. If you assume evil bugs were here before the problem began, it's the same as assuming nature cannot change. Nature can (and does) change.
