Ah, that's a tough one. It's mixing apples and oranges, and neither thing is rooted in fact to begin with. Belief in God (which god?) is an irrational "belief in" something - which doesn't mean it's not true, but it does mean we can't prove it. Evil can be both a religious concept or a secular observation of people's emotional makeup. It's a lot more rooted in science, though what you call it and what you attribute it to are not clear. In my estimation, you could choose any side to this but arguing for it, which means presenting credible evidence, is going to be slim pickings. I don't know how your teacher might respond to what I've just said, but it might demonstrate at least that you've put some thought into it, which is, after all, the (supposed to be) whole point of the exercise. You could also consider taking on the assignment and running it through what YOU think - that too is one of the main points of education - to introduce you to the idea that YOU TOO can think - and that your considered thought is valuable too. It is, you know. What do you, in fact, think? This is your opportunity to say.
