I have said it before but I think that the disasters that have recently rocked Japan are evidence enough of my point: an atheistic worldview makes a lot more sense. In fact, the world makes a lot more sense when you take God out of the equation. A naturalistic worldview sees the world for what it is; a self sustaining natural occurrence. The world is full of apparent order and chaos in the many varied elements of nature. But when natural disasters strike we have only two choices to help us understand them; the natural and the supernatural.
In my view trying to insert a why alongside a deity into a natural disaster just creates more questions than answers. Trying to understand the mind of "God" is an exercise in futility. The bible itself teaches that Jehova is a jealous God, hell it's even in the ten commandments. I've heard fundamentalist's idiots attribute these natural disasters to punishment for violating the commandments where God demands that you worship only him. Paganism and idolatry are the fundamentalist's first choice to try and understand how a nation or country can suffer so much tragedy throughout its history.
The next favorite religious reason is that all of these natural disasters are just signs of the coming of the Lord Jesus Christ. As I have stated many times if this were the case then it seems that God must keep changing his plans at the last moment. There have been wars and rumors of wars and natural disasters all throughout the history of mankind and even before we came along this planet still displays the scars of its chaotic past.
Fundamentalists Christians seem to rejoice every time they see these so called "displays of God's power" when in fact they should feel compassion and love for their fellow man. The biblical story of Jonah in my opinion is an allegorical narrative of this idea. Jonah was told to go to Ninevah to tell them to repent or else God would destroy their city. He refused because he did not like the Ninevites and went in the opposite direction on a ship. When the ship was in danger of capsizing due to God's anger at Jonah for not obeying his commands; Jonah informed the superstitious crew about his predicament and they cast him into the sea. He was then swallowed by a large fish ( the bible does not say it was a whale)and carried to the shores of Ninevah where he then carried out his mission. The inhabitants of Ninevah repented and God forgave them and did not bring destruction and disaster to their city. You can read about it in the book of Jonah chapters 1 through 3.
Back to the topic at for I digressed a little in the last paragraph. I feel that natural disasters are just that, natural. There is no need for a supernatural explanation. Scientists know why and in most cases how they occur without the need for something as silly as the wrath of God. Plate tectonics help us understand why earthquakes occur. When they occur at sea the shock waves create huge waves in the water which in turn become tsunami's. Now Japan faces a new threat and this one is entirely man made. The threat to their nuclear reactors and the release of radiation into its atmosphere. We could only hope that this situation will not get any worse and help out in any way we can to help relieve the suffering of our fellow man.
