“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.”

I believe in Spinoza's god, who reveals Himself in the lawful harmony of the world, not in a god who concerns himself with the fate and the doings of mankind.
-- Albert Einstein
Part of a one-and-a-half-page letter, written in 1954 in German and addressed to the philosopher Eric Gutkind.
In 1936 a sixth grade girl wrote to Einstein asking if scientists pray. Here is his response:
Dear Phyllis,
I will attempt to reply to your question as simply as I can. Here is my answer:
Scientists believe that every occurrence, including the affairs of human beings, is due to the laws of nature. Therefore a scientist cannot be inclined to believe that the course of events can be influenced by prayer, that is, by a supernaturally manifested wish.
However, we must concede that our actual knowledge of these forces is imperfect, so that in the end the belief in the existence of a final, ultimate spirit rests on a kind of faith. Such belief remains widespread even with the current achievements in science.
But also, everyone who is seriously involved in the pursuit of science becomes convinced that some spirit is manifest in the laws of the universe, one that is vastly superior to that of man. In this way the pursuit of science leads to a religious feeling of a special sort, which is surely quite different from the religiosity of someone more naive.
With cordial greetings,
your A. Einstein
