Humans have learned throughout the existence of the cosmos to avoid suffering caused by these types of "evils". They have either adapted to their environment or avoided the environment completely. Very few people still suffer from the evils of dangerous animals anymore because they have learned to identify and therefore avoid them effectively. Regarding the "problem" of hostile environment, we have learned to adapt our immediate environment through shelter, clothing or simply moving somewhere where life is easier. That's not to say that every undesirable situation has resulted in such an event. .
After identifying these evils we must now ask: "Why would god create a world with the potential for so much suffering?" Hick's answer to this involves interpreting the creation story in Genesis in a non-literal fashion. Rather than regarding the story as an account of what has already happened, he suggests that we consider it an account of what is currently taking place, (Mill and Hick). The idea here is that we are the only integral part of God's creation. Hick believes that we have not yet reached the final "day" of creation. Regarding the Earth this way helps us see the possibility of it being a "factory for making souls". Being created in a world where this belief is held requires the possibility that we suffer in order to provide incentive for improvement. God in a way is still creating humanity, using the tools that he has shaped throughout the history of the cosmos. .
Does the existence of disease and death need to be attributed to the evils of the world, thus the cosmos and thus God? It is very easily argued that death is not a by-product of evil, more it is a part of life. One cannot avoid death, that is what makes us mortal and thus not God. What we choose to do with our time on Earth is far more important than what pulls us away. Perhaps the amount of suffering that leads up to death and the suffering after death needs some further explanation, but the pure existence of death should not be considered an evil.
