Tine should exist before space. All basic particles are just points that occupy no space. we can only detect them by physical laws Therefore, if we pack them all together, they occupy no space, And all their physical properties of them are canceled out. We can't detect them in any physical way, This group of basic particles is the beginning point of the whole universe. As time exists at this strange point. We can deduce there is a physical law called creation existing at this point. At a certain point of time, the whole universe is born to disintegrate this group of basic particles by this creation law.
