Some interesting people have had similar thoughts as Einstein.

Abraham Lincoln, the 16th President of the United States disagreed with Christianity in his youth and
in later years confirmed this when he said. "My earlier views of the unsoundness of the Christian
scheme of salvation and the human origin of the scriptures, have become clearer and
stronger with advancing years and I see no reason for thinking I shall ever change them."
He also said. "The Bible is not my book nor Christianity my profession."

John Adams, second President of the United States, said. "The divinity of Jesus is made a convenient cover for absurdity."
And. "This would be the best of all possible worlds, if there were no religion in it."

Thomas Jefferson, third President of the United States and principal author of the Declaration of Independence said. "Millions of innocent men, women and children, since the introduction of Christianity, have been burned, tortured, fined and imprisoned. What has been the effect of this coercion? To make half the world fools and half hypocrites; to support roguery and error all over the world..."
And. "The Christian God is a being of terrific character - cruel, vindictive, capricious, and unjust."

I like these quotations from some well known identities.

George Bernard Shaw: "The fact that a believer is happier than a sceptic is no more to the point than the fact that a drunken man is happier than a sober one."

Sigmund Freud: "Religion is comparable to a childhood neurosis."

Mark Twain (Samuel Langhorne Clemens) was critical of organized religion and certain elements of Christianity. Some of his sayings are.
"God's inhumanity to man makes countless thousands mourn."
"God, so atrocious in the Old Testament, so attractive in the New - the Jekyll and Hyde of sacred romance."
"One of the proofs of the immortality of the soul is that myriads have believed in it. They have also believed the world was flat."
"I am quite sure now that often, very often, in matters concerning religion and politics a man's reasoning powers are not above the monkey's."
