Notice that among all of those things that "aren't physical" you didn't describe a person or creature or any other being. If your point is that god is just an abstract concept that only exists so long as we conceptualize him in some way, that's fine. So is Zeus. So is James Bond. So is the Tooth Fairy. Good job proving the existence of every fantasy character that we ever thought up. The world just became a truly interesting place.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
