A couple of links via butterfliesandwheels.com: Francis Crick says, "The god hypothesis is rather discredited." He also

argues that since many of the actual claims made by specific religions over 2,000 years have proved false, the burden of proof should be on the claims they make today, rather than on atheists to disprove the existence of God.

His colleague James Watson agrees, "Every time you understand something, religion becomes less likely."

In 1961 Crick resigned as a fellow of Churchill College, Cambridge, when it proposed to build a chapel. When Sir Winston Churchill wrote to him pointing out that "none need enter [the chapel] unless they wish", Crick replied that on those grounds, the college should build a brothel.

Meanwhile, Christopher Hitchens' Holy Writ:

Religion of every kind involves the promise that the misery and futility of existence can be overcome or even transfigured. One might suppose that the possession of such a magnificent formula, combined with the tremendous assurance of a benevolent God, would make a person happy. But such appears not to be the case: unease and insecurity and rage seem to keep up with blissful certainty, and even to outpace it.

That just about says it all.
