The Cosmos and the Soul of the Cosmos

Stoics say god and the soul are physical things which spread all the way through other physical things. But how is this possible? It seems to presuppose something absurd, namely that two physical objects can be in the same place at the same time. If only this were true, it would solve all our housing problems. Each physical object seems jealously to guard its own space. Some kind of force is needed to push it out of its place to make room for something else.
