Nobody saying there is a god or soul, but explanation can be in unknown parts of physics and surprisingly we have that unknown parts.

We have unexplained phenomenon - consciousness, everyone (well, at least me) experience it. We don't have the mechanism for it, so we reject that phenomenon exists. I don't think it's a good idea to outright reject hypothesis, that have evidences behind it, but don't have a mechanism. Remember what happened to theory of washing hands for surgeons or to continental drift (it took half a century for it to be taken seriously!)
