We see many details, and we want to know how they fit together. That is what science is all about. Scientists look at the details and try to find out how they all cohere. Think, for example, of creativity. This is in contrast to the animals about us.
People also fear death, and they have the aspiration to truly choose.
Incidentally, even those who in their writings say we only think we choose quickly fall into words and phrases that only make sense if they are wrong and we do truly choose. Human beings are also unique in that they verbalize. That is, people put concrete and abstract concepts into words which communicate these concepts to other people. One could name other factors, but these are enough to differentiate people from the other things in the world. There is a remarkable parallel between the way scientists go about checking to see if what they think about reality does in fact correspond to it and the way the biblical world view can be checked to see if it is true.
