I talk using phrases similar to your quotes from Einstein, without meaning quite what you take him to mean in your paraphrases there. I sometimes use God references when I talk just like Einstein did - similar wording and all - but I am atheist in your sense of deity. When I read that stuff from Einstein I simply read it as I would from anyone else with a similar cultural background and education, and basically atheistic as he appears to be, as I am, and as most people of his general background and approach who talked like that would be, by presumption. We all could be wrong, of course, and Einstein could be an odd exception, but why would one bet that way?
