Some people still don’t get it, therefore I let the greatest humans speak:

“Religion is excellent stuff for keeping common people quiet.” — Napoleon Bonaparte

“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. No interpretation no matter how subtle can (for me) change this.” — Albert Einstein

“I have never seen the slightest scientific proof of the religious ideas of heaven and hell, of future life for individuals, or of a personal God. So far as religion of the day is concerned, it is a damned fake: Religion is all bunk.” — Thomas Edison

“When a man is freed of religion, he has a better chance to live a normal and wholesome life.” — Sigmund Freud

“The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church.” — Ferdinand Magellan

“I do not fear death. I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it.” — Mark Twain

“If we are going to teach ‘creation science’ as an alternative to evolution, then we should also teach the stork theory as an alternative to biological reproduction.” — Judith Hayes

“The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge, and there’s no place for it in the endeavor of science.” — Carl Sagan

“We would be 1,500 years ahead if it hadn’t been for the church dragging science back by its coattails and burning our best minds at the stake.” — Catherine Fahringer

“The fact that a believer is happier than a skeptic is no more to the point than the fact that a drunken man is happier than a sober one. The happiness of credulity is a cheap and dangerous quality.” — Bernard Shaw

“There may be fairies at the bottom of the garden. There is no evidence for it, but you can’t prove that there aren’t any, so shouldn’t we be agnostic with respect to fairies?” — Richard Dawkins

“Atheism is a requirement for a complete human being. Religion is a crutch that is shackled to you, one you never really needed in the first place, but were convinced by others that you couldn’t live without. Once you discover it’s only an illusion, that it’s not even a real crutch, you discard it gladly.” — Brent Yaciw

“The only difference between a cult and a religion is the amount of real estate they own.” — Frank Zappa

“A lie is a lie even if everyone believes it. The truth is the truth even if nobody believes it.” — David Stevens

“Men rarely (if ever) manage to dream up a God superior to themselves. Most Gods have the manners and morals of a spoiled child.” — Robert A Heinlein
