Spiritually, humans are set apart from other mammals because they were created in God's image and given custody over His creation.
Humans are more intelligent and culturally sophisticated than other species (see man). This is evident in several unique traits:
- An unsurpassed depth of communication, in art as well as language.
- The ability to understand abstract concepts.
- Detailed and abstract concepts of morality.
- A understanding of the nature of sin.
There are an estimated 6.8 billion humans.
