"I can't answer with a simple yes or no. I'm not an atheist and I don't think I can call myself a pantheist. We are in the position of a little child entering a huge library filled with books in many different languages. The child knows someone must have written those books. It does not know how. The child dimly suspects a mysterious order in the arrangement of the books but doesn't know what it is."

This one has been contested lately though. Here's the full story. Most of the objections seem pretty weak and the fact Einstein didn't disavow it and partially confirmed it leads me to believe it's most likely accurate. It was also included as part of his biography that was released a couple years back so objections are certainly part of the fringe opinion.
