From my short stint as God in the seventies, I am allowed to tell you about your universe.
It is an atom, inside the wooden leg of a chair. All the other atoms in that leg are also universes, and indeed are all the atoms where the chair is situated.
Which is in a small country cottage in an area not entirely similar to Dorsetshire.
And naturally, every atom inside you, and all that surrounds you, is also a complete universe, in which there are huge woodeny things like chairlegs each containing trillions of universes.
Take care of that chair.
