“There are only two choices: Either no one created everything out of nothing, or Someone - and intelligent, omnipotent, eternal First Cause - created everything out of nothing. Which makes more sense?”

Ralph M. Hawtrey as assistant secretary of the British Treasury, quoted in: Robert Latham Owen (1939), National economy and the banking system of the United States. p. 102

Last interview (1980)
Context: I’m 40, I wanna talk to the people my age. I’m happy if the young people like it, and I’m happy if the old people like it, I’m talkin’ to guys and gals that have been through what we went through, together — the sixties group that has survived. Survived the war, the drugs, the politics, the violence on the street – the whole she-bang – that we’ve survived it and we’re here. And I’m talkin’ to them. And the "Woman" song is to Yoko, but it’s to all women. And, because my role in society – or any artist or poet’s role – is to try to express what we all feel. Not to tell people how to feel, not as a preacher, not as a leader, but as a reflection of us all. And it’s like that’s the job of the artist in society, not to... they’re not some alienated being living on the outskirts of town. It’s fine to live on the outskirts of town, but artists must reflect what we all are. That’s what it’s about – artists, or poets or whatever you wanna call it. And that’s what I’m tryin’ to express on behalf of all the men to all the women, through my own feelings about women – when it dawned on me, "God! It is the other half of the sky" as the late-great Chairman MacDougal said, right? I mean, they are the other half of the sky, and without them there is nothing. And without us there’s nothing. There’s only the two together creating children, creating society. So what’s all this B. S. about, you know, "women are this" and "men are that" – we’re all human, man. We’re all human. And, I am tryin’ to say it to Yoko, but to all women, you know? On behalf of all men, in a way. If that’s taken it too much on meself, I feel that artists are that – they’re reflections of society... Mirrors.

As quoted in Journal of France and Germany (1942–1944) by Gilbert Fowler White, in excerpt published in Living with Nature's Extremes: The Life of Gilbert Fowler White (2006) by Robert E. Hinshaw, p. 62. From the context http://books.google.com/books?id=_2qfZRp9SeEC&lpg=PP1&pg=PA62#v=onepage&q&f=false it seems that White did not specify whether he had heard Einstein himself say this or whether he was repeating a quote that had been passed along by someone else, so without a primary source the validity of this quote should be considered questionable.
Some have argued that elsewhere Einstein defined a "miracle" as a type of event he did not believe was possible—Einstein on Religion by Max Jammer (1999) quotes on p. 89 from a 1931 conversation Einstein had with David Reichinstein, where Reichinstein brought up philosopher Arthur Liebert's argument that the indeterminism of quantum mechanics might allow for the possibility of miracles, and Einstein replied that Liebert's argument dealt "with a domain in which lawful rationality [determinism] does not exist. A 'miracle,' however, is an exception from lawfulness; hence, there where lawfulness does not exist, also its exception, i.e., a miracle, cannot exist." ("Dort, wo eine Gesetzmässigkeit nicht vorhanden ist, kann auch ihre Ausnahme, d.h. ein Wunder, nicht existieren." D. Reichenstein, Die Religion der Gebildeten (1941), p. 21). However, it is clear from the context that Einstein was stating only that miracles cannot exist in a domain (quantum mechanics) where lawful rationality does not exist. He did not claim that miracles could never exist in any domain. Indeed, Einstein clearly believed, as seen in many quotations above, that the universe was comprehensible and rational, but he also described this characteristic of the universe as a "miracle". In another example, he is quoted as claiming belief in a God, "Who reveals Himself in the lawful harmony of the world."
