With your minds so closed off to creation there is very little explanation to be had there. My religion believes that all God created was good, and that bad things came about from perversion of what was good.(perversion isn't always sexual) Like Satan for example, we believe that it was out of jealousy that Lucifer turned away from God and tried to oppose him. God created Lucifer as sort of a top angel, well i'd better cut it short. Lucifer means morning star but Satan means enemy. The only reason Lucifer was able to be consumed by his jealousy was because he had traits of God to begin with. Exodus 20:5 says that God is a jealous god. This jealousy was more of a protective, caring jealousy, but Lucifer perverted it into the coveting type of jealousy we think of today. When he was banished to Earth began perverting all kinds of things rather than just character traits. The introduction of sin and evil led to hostility between creatures, they begain to kill and eat one another, the smallest forms began to become harmful rather than helpful and functions of the human body began to become less efficient as time progressed. Things don't work the way they used to. Meat was never meant to be eaten,things were never meant to die. Eating meat is not a sin but we eat it because of sin, just like dieing is not a sin but we die because of sin. Anything can go wrong now, such as an uncontrollable overproduction of healthy cells(cancer) or insulin resistance(diabetes). Bottom line is that God did not create bad things. The things God created became bad. (Im an SDA btw)
