The human body appears to have evolved. However, as human beings, we differ fundamentally from animals. Whereas animals are content with being what they are, humans seek something beyond finite, created things.
Our partially abstract desire for ultimate happiness – a happiness that goes beyond what we can see here and now – supports the idea that we have an immortal soul. The soul is what makes us ourselves, and enables us to consciously choose good or evil. Our soul is created by God. Evolution deals with the body; the Creation story gives us insight into what is housed in that body: the soul. Both are necessary if we want to better understand the world as God has created it.
