I disagree with that. Animals live purely for survival. Humans have developed consciousness and intellect so we have the ability to question things. So no, we don't just survive to survive. Our lives may not have a predestined meaning but we (well few of us) are capable of finding our own meaning, and that is because of our ability to think. So while we do live for dopamine, we don't just do it for survival, like animals do. And I do believe in a higher force. We discovered virus, bacteria, cells and even atoms. If such small things can exist that we can't see, things like GOD may certainly exist.
I agree that we chase for dopamine to distract from things that are tedious and unpleasant but I also believe that we have a capability to think deeper. That's how people discovered meditation. And meditation is far away from dopamine.
