I cannot recall that I ever had a complete picture of what god was. I understood that he was a person, with a body and a mind and thoughts and feelings and motivations of his own. Very human, in that respect. But I doubt that I could have explained what he was made of, and probably would have gone with something like "spirit" that would have required a definition all its own. I don't recall any Christian that I knew that would have felt any differently. If you believe god exists and is out there, defining him aside from his attributes/motivations/desires doesn't seem terribly important.
"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."
