Also, nice heads up, chad_tukes, for setting the record straight on Einstein's views about God. However, he did made statements that were liable to be misinterpreted. As such, we've seen apologists who try to conscript Einstein to their religious camps by wrongly misinterpreting his quotes.
For example, he gave this statement to Time magazine explaining this belief that man could not understand the nature of God:
I'm not an atheist. I don't think I can call myself a pantheist. The problem involved is too vast for our limited minds. We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangement of the books but doesn't know what it is. That, it seems to me, is the attitude of even the most intelligent human being toward God. We see the universe marvelously arranged and obeying certain laws but only dimly understand these laws.
and then years later, he clarified his stance....
The word God is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this. These interpretations are highly manifold according to their nature and have almost nothing to do with the original text. For me the Jewish religion like all other religions is an incarnation of the most childish superstitions. And the Jewish people to whom I gladly belong and with whose mentality I have a deep affinity have no different quality for me than all other people. As far as my experience goes, they are also no better than other human groups, although they are protected from the worst cancers by a lack of power. Otherwise I cannot see anything 'chosen' about them.
Clearly, when Einstein used the word "God", he seemed to be referring to it in a metaphorical sense...like when he commented on the weirdness of Quantum Mechanics with this famous quote: "God doesn't play dice with the universe." The reason he said this was because he believed that the universe is predictable and can be known. But, as far as the God in religion is concerned, he certainly made his position very clear.
