Firstly, I appreciate your kind and thoughtful answer.
More importantly, I thoroughly commend the intellectual honesty when you said this:
> But the question "if God exists, why did he create a world with earthquakes" is an interesting question. I don't have any idea how any religion would approach this question.
To be clear, I wasn't hoping for a handy solution to one of life's "big questions" in an HN comment.
I was just pointing out that your response to the Epicurean argument was a bit narrow in the assumed scope of the assumed interpretation of the Epicurean argument.
Cheers.
