“I believe in Spinoza’s god, who reveals himself in the lawful harmony of all that exists, not in a god who concerns himself in the fate and doings of mankind”. Albert Einstein
Einstein wondered at the intricate rationality of the universe. It persuaded him that “something” must have laid down the basic structure, physics and chemistry that is the basis of the billions of galaxies and stars (and maybe the multiple universes). Whether you call this force a prime mover or designer, “it” has avoided the detailed outcome, allowing evolution to make a host of mistakes and reach many dead ends, before life as we know it on our little planet reached its present, still unsatisfactory, state. Thus, I personally would not like to bet against a prime mover, but agree with both Einstein and Epicurus than such a force takes not the slightest interest in the inconsequential lives of human beings.
It is a fact that Epicurus did not question the existence of the gods. He just denied that they involved themselves in individual lives. Great minds think alike.
