Computers vs Humans

What separates a human from a computer? It isn't the ability to move or think like a human, those things can be programmed. It isn't the logical thinking that is unique to the human animal, because even that is performed better in a computer than in a human. I believe that what separates us from a computer or a robot is our soul. The one thing that a computer cannot have is a relationship with a higher being. Sure, we can teach a robot or program it to "pray", cry, or speak on behalf of a certain religion. But it cannot truly know a God and communicate with a higher power, meaning it has no afterlife, no sin, and nothing that comes with a religion that a human is capable of possessing. One interesting thing that was talked about in class is the way that these computers can be programmed to act like a human down to the smallest human movement, such as a blink. In class, we tried to come up with something that a human can do (other than bleed, reproduce, eat, etc) that a computer cannot be programmed to mimic. One thing that was mentioned was that a computer cannot have true feelings on a subject. It can mimic a feeling or know to act happy or sad, however it does not truly feel these things. Another interesting point brought up was if a robot can experience love? Does this coincide with the idea of a robot not having a soul, something innate and unique to humans?
