Sorry to but in.
The Tao Te Ching is a great read... well, it depends on the translation you use. Taoism (he philosophy NOT the religion) is atheistic and makes a lot of sense.
I agree completely with your points.
I would add that the Tao is atheistic but not necessarily a-deistic, if you get my drift. The Tao, while not being supernatural is, to some degree, supernormal.
There is an old saying (actually about Zen but close enough): "It is just like everyday life only about 2 inches off the ground."
