Does God exist? If God doesn't exist than the answer is simple. Yes, we can live without God. Does God exist, than we are in God (as a God is and must be omnipresent, so also there where we are), and being in God we cannot be without God. But we are, so there are to possibilities. There is no God or it doesn't matter where you believe in for your existence. People saying to live without God seem to have a life, even a nice life maybe. I believe that there are two levels of being 'in God.' There is a physical level. Physicly we are in God. But many are not 'one mind with God.' Many do not what God supposes. So, on that second level it is possible. On the first level it is not.
