Hu Man

I do not know how to define it. I can not decide if it will be science that defines us as humans,  or the church. Science can define what is human material from animal in DNA. The church defines us as human from animals because we have a soul. Which one has more proof? Is it our intelligence that gives us a soul? Or something else? I am more inclined to believe that science has the upper hand on what is a human, however, they can not explain the soul.
