Glossing over the fact that, as double-m points out, this has been covered to death by teenage faux-philosophers and scholars alike already
The simple answer (or at least, what might be considered the religious get-out clause) is that you entirely misunderstand what is meant by omnipotence, omniscience and benevolence in regard to a god.

Omnipotence in the form you believe it to be, after all, is impossible, even if you believe in a beardy sky wizard. Take the challenge - "i want you to create an object so heavy you can't pick it up"

Can't do it? well, you aren't omnipotent. Can do it? ah, well, you can't pick it up, so you aren't omnipotent either.

Christian scholars will tell you that your mistake in the above is to ascribe human meanings incorrectly. Or, that the definition of divine omnipotence is that God can do anything that it is in his nature to do.

Ditto ominscence and benevolence.

If you want to see the scholarly version of your explanation above, it's David Hume "the problem of evil" that you're looking for. But it won't make a jot of difference to Christians, who quite rightly say the entire premise for this being a logical fallicy is flawed to start with.

Not that I believe in God, mind you. Just some philosophers are every bit as much cocks as the church.

I never could quote my sources.
I'll just cite you, in future.
