An alternate explanation is not a refutation.

If Darwinism is true, then there is no purpose or meaning to life, there is no morality, there's no qualitative difference between humans and animals, there's no life after death, and there's no purpose to human history. Now, are you trying to tell me that it doesn't really matter if people believe we evolved or not?

If the unborn is a human person, no justification for abortion is adequate.

People are tempted to think (understandably) that if God were really good He'd never allow any evil in the world at all. But I don't think a perfectly good God would never permit any evil, and neither would others, I wager, if they thought about it. Rather, I think that a good God always prevents suffering and evil unless He has a good reason to allow it. That's the crux.

I want people to see that Christianity claims to be true in the deep sense, and if it isn't, then it solves nothing at all.

In matter-ism (materialism), there can be nothing wrong with the world since there is no right way for the world to be in the first place. Everything is just matter in motion and that's that. In Mind-ism (monism) there's a different route to the same problem. There cannot be a problem of evil, even in principle, since in Mind-ism even morality is maya; illusion. In neither story, then (if we're to be consistent with their principles), can the issue of evil be raised. But in real life the problem comes up all the time. That's the difficulty.

Sometimes (at least in principle) God might allow some evil because doing so will prevent a greater evil, and sometimes He might allow evil because it will produce a greater good.
