We now understand god thanks to science. God is a human constructed concept that was our initial attempt to explain the world and to give us meaning and purpose. Science and logic has shown us that the concept of god is not self consistent or logically sound and contradictory to the observed universe. It does have a long history and many cultures are built around the concept of god(s) so it will take some period of time for us to wein ourselves away from its hold on our imagination. The sooner the better.
