If you were to ask an atheist about how the universe, life itself, and all that exists came to be, the answer would be scientific. Scientific study requires a key element, observation. And after extensive study through observation, atheists conclude that there is no God, or rather, there is no proof that God exist. Thus they conclude, through scientific study and observation, the origin of the universe, life itself, and all that exist. This being the case, how does an atheist view emotions? Love, happiness, sadness, laughter, etc. Where are these emotions derived from? What is it's origin? For if we look through a microscope, we can see atoms, microorganisms, etc. But you can not see sadness. Or happiness. Or love. So where do these emotions originate from and derive from, if not the human soul? And how do you know where it's derived from, if you can't see it? This alone should demonstrate that it's origin and where emotions are derived from is not visible as well, thus the human soul. Many atheists say that there is no proof of God because no one can see God. Yet they have no delay in accepting that humans have emotions, yet they can not look inside any body and see emotions. A contradiction. How do atheists explain this?
