Its obvious you don't read before you type. Don't feel bad, many of the believers in this thread have done the same thing.
Atheists read all of the comments?
What you are calling natural evil, is basically nature and circumstance. It's possible, very possible that neither you, nor I are going to understand these things before we reach the end of our lives. Some things are mysteries to us now. When I was a child, I thought I had to know the answers to all of life's questions. I was too young to understand that there aren't answers, that we are privy to, for all of life's questions. Sadly, when I was a teenager and very vulnerable after the death of my brother, some people came along who claimed they knew the answers. They worked on me for most of a year, answering question, after question. Now I understand that if anyone thinks he or she can ever find all of the answers, he or she might as well tattoo the words: Control Me. Please. right across the forehead. I don't know how God participates or doesn't participate when it comes to things like tsunamis and their aftermaths. I'm not going to pretend to.
I recall being at the funeral of my ten year old friend. She had died in a housefire. One of the church ladies tried to comfort me by telling me that God saw the prettiest flower in his garden and decided to pick her and take her home with him. I remember thinking, "I appreciate that you are trying to comfort me, but that's a silly explanation for what happened to Ann." I knew that God had nothing to do with my friend's death. I was ten years old at the time.
