I happen to be a Christian, and an educated one at that.
Comeon, you are taking the Bible too literally. You've been listening to too many Catholics
Dust is a metaphor - it doesn't mean God literally took dust and made Adam and Eve, but that he took what is best described as gas - organic particle gasses - and fashioned living humans from it. The Bible can't go into scientific descriptions of the exact specifics of the Creation.
Once again, these things are metaphores. God "said" "let there be light" and the Sun "appeared." The Bible makes absolutely no mention of how the Sun "appeared," how long it took, etc. The Sun, IMO, appeared through a condensation of simple particles through gravitational attraction and then gathered enough excess heat energy to initiate a fusion reaction, which triggered an outburst of light energy, hence the appearance of light. And all this happened because God wanted it to.
God allows events like Katrina to happen for different reasons. Perhaps it was a test. Perhaps it was punishment. Perhaps it is atonement. IMO, it's best not to try to interpret the will of God.
Who's to say what's perfect? God is perfect is His way, not in our human perceptions. What is perfect to you? Do you even know the definition of it? What would you expect of a perfect God?
He did not make us do sins. We chose to do them ourselves.
Because He doesn't want us to. He wants to give us free will. Free will is one of the bases of humanity.
