Storm-Rider @ 138 claimed that Einstein was not an atheist and linked a comment from Time Magazine to support his point.

The following link from an atheist website lists various Einstein quotes that indicate Einstein was an atheist:

The story that I was told when I was a physics undergraduate was that Einstein gave up on religion after he was convinced of basic quantum theory’s irrefutable validity. Again, I believe Einstein was in error to base his atheism upon the validity of quantum mechanics. IMHO, quantum mechanics is a consequence of the universe having an intrinsic “thickness” also called the “Planck Length”. This thickness is orthogonal to the three spatial dimensions (think four dimensionally) and associated with time.

“I was referring to String Theory as one attempt to parse the GUT problem. String Theory is a branch of quantum mechanics, or more accurately, quantum chromodynamics, both of which are subsets of theoretical physics.”

Skepticism of String Theory makes perfect sense (I agree with you!). However skepticism of basic quantum theory makes no sense at all. The agreement between the quantum theoretical description of atomic hydrogen and experimental evidence is arguably the greatest success story of modern science. For the specific case of atomic hydrogen, physicists can match theory and experimental data to an amazing number of digits. String Theory on the other hand has been the province of sly hustlers and charlatans like Michio Kaku. Whole books have been written about the utter nonsense of String Theory, e.g. “Not Even Wrong: The Failure of String Theory and the Search for Unity in Physical Law” by Peter Woit.
