My belief is that God tests people's faith and gives them a chance to go good deeds, such as helping out those who have been affected by such disasters.
But God is omnipotent, and thus knows the past, present and future, and so knows the outcome anyway, surely?
It's all gibberish. "1.If an all-powerful and perfectly good god exists, then evil does not." Well that basically says that god doesn't exist. There is evil in this world, so on the logic of this statement, there is no perfectly good god.
We've spent 2,000+ years looking for evidence of God and no one has unearthed any evidence. I think it might be time we stopped wasting our energies on this pursuit and move on to something else.
Even the normally genial David Attenborough got involved. "Free will is not the only cause of evil in the world. For instance, David Attenborough often tells this story: My response is that when Creationists talk about God creating every individual species as a separate act, they always instance hummingbirds, or orchids, sunflowers and beautiful things. But I tend to think instead of a parasitic worm that is boring through the eye of a boy sitting on the bank of a river in West Africa, [a worm] that's going to make him blind. And [I ask them], 'Are you telling me that the God you believe in, who you also say is an all-merciful God, who cares for each one of us individually, are you saying that God created this worm that can live in no other way than in an innocent child's eyeball? Because that doesn't seem to me to coincide with a God who's full of mercy'."
