I have not studied about dark matter and dark energy. There is also antimatter.
By material world, I imply all the phenomenon, which have been observed or are observable or are perceivable, directly or indirectly. It, of course, includes all those things, as well, which are currently beyond the means of our observation.
We have also to distinguish between the observation data and a scientific hypothesis, interpretation or theory. On the basis of same available data, more than one theory or interpretation can be formulated. As is the case of a number of alternate interpretations of the quantum phenomenon.
As I already said that the question of God, being of metaphysical nature, essentially, falls beyond the scope of science and is addressed by philosophy, religions and mysticism.
My belief is that human being would never ever be able to full comprehend and fathom even the material world. It would remain an unending journey and our knowledge would always remain partial and fractional.
