What does this statement mean The intellect and free will make the human being superior than all other creatures?

The intellect

our intelligence. You know our brain with the ability of higher levels of thinking basically being able to think complex thoughts and debating philosophy. Because for example a cat doesn't have a philosophy it wakes up and eats poops and sleeps.

Free Will

For Christians this is the ability that god gives them to make decisions in the "test" of life. Because they believe that god is all powerful on one hand and on the other there like well he doesn't interfere with free will. So its a cop out big enough for the titanic lumbering god of Christians to slip himself through.

And Christians then deduce that makes us better than all other living creatures
