If Einstein did not believe in a god, and he did not believe in any spiritual life force, and he was not affiliated with any religion, and he says he is not an atheist, then doesn't that leave pantheism as his only option (he said himself that he was a follower of the natural, or cosmic religion, which sounds pretty pantheistic itself). And remember, pantheism is basically using god as a metaphor for nature, and i would assume Einstein would claim to believe in a natural pantheistic god, if only because it contained the word god, in order to keep up his public appearance, which would be necessary for his credibility, and also because a religious person would be more likely to trust someone who believed in a 'god' then someone who didn't, even if this god wasn't a god in the conventional sense (just a theory). In any case, it is evident that he would have to be pantheistic, which, when compared to insane fundies, is a good as atheist (although atheists tend to have more of a spark when defending the fact that god/spirit/heaven/hell/other crap doesn't exist).
