Sin and death are a result of the Fall of Man (i.e. Adam and Eve's sin in Eden), which itself followed from humanity's free will. These were not present in creation as God originally made it.

Humans evolved, they were not created. Zeus defeated the Titans and brought a new and fiery earth into order.

There are no good and evil.
Only order and chaos.

There is no heaven or hell.
Beyond death there is nothing.

The is no objective morality.
Only the law of the victor.
